Applies same logic to general Tegra pincontrol driver as is done to Tegra20

Tegra20 driver doesn't know about some pin configurations and even about
some pins. In case when pin configuration is unknown the pin would be
muxed to whatever is under function 0, in case when pin itself is
unknown, it could cause out-of-bounds array access in pinmux_set_func
and pinmux_set_pullupdown.

Tom Rini <trini@konsulko.com> says:
This series switches to always using $(PHASE_) in Makefiles when
building rather than $(PHASE_) or $(XPL_). It also starts on documenting
this part of the build, but as a follow-up we need to rename
doc/develop/spl.rst and expand on explaining things a bit.

It is confusing to have both "$(PHASE_)" and "$(XPL_)" be used in our
Makefiles as part of the macros to determine when to do something in our
Makefiles based on what phase of the build we are in. For consistency,
bring this down to a single macro and use "$(PHASE_)" only.

We have three warnings about needing to use quotes around some strings
in Kconfig files today. In two of these cases we can just add the
missing strings. In the case of INTEL_PINCTRL_PADCFG_PADTOL the symbol
is never referenced and should be dropped.

Assorted fixes, refactorings and additions that are ready, and shave
off some load from upcoming series'.
Improves MMC performance on D1/T113 (missed clock divider), enables
eMMC access on the H616 family (never worked, many thanks to Jernej for
the fix!), DRAM detection fixes for the H616 (now reportedly stable).
Some patches for the upcoming Allwinner A133 SoC support: a few
refactorings, plus the DM clock and pinctrl driver. The DRAM init
routines work, but need some more polishing, that also holds back the
actual enablement patch, which will hopefully follow for v2025.07 still.
Also some preparatory patches for the Allwinner A523 SoC support, for
now just to improve the FEL save/restore code. There will be more patches
coming up for this, ideally also in the coming cycle still.
Gitlab CI passed, and I booted that briefly on some boards.
The Allwinner A100 SoC has been around for a while, and has now seemingly
been replaced with its close sibling A133.
Add the required mapping between the pinmux group strings and their
respective mux value, as far as used by U-Boot proper. Linux has some
basic (clock and pinctrl) support for a while, so we can build on the
names already used there.

Presently, get_function_mux returns an unsigned int and cannot
differentiate between failure and correct function value. Change its
return type to int and check for failure in the caller.
Additionally, updated drivers/pinctrl/qcom/pinctrl-*.c to accommodate the
above return type change. Only compile test done.

The RZN1 symbol name is CONFIG_RZN1, there is no CONFIG_ARCH_RZN1.
Since RZN1 enables CONFIG_ARCH_RENESAS as well, remove the special
RZN1 entry from Makefile, the RZN1 pinctrl driver will still be
pulled in via CONFIG_ARCH_RENESAS.

The pinmux bits for GPIO2-B0 to GPIO2-B6 actually have 2 bits width,
correct the bank flag for GPIO2-B. The pinmux bits for GPIO2-B7 is
recalculated so it remain unchanged. Add missing GPIO3-B1 to GPIO3-B7
pinmux data to rk3328_mux_recalced_data as mux register offset for these
pins does not follow rockchip convention.
This matches changes in following Linux commits:
- e8448a6c817c ("pinctrl: rockchip: fix pinmux bits for RK3328 GPIO2-B pins")
- 5ef6914e0bf5 ("pinctrl: rockchip: fix pinmux bits for RK3328 GPIO3-B pins")

U-Boot pinctrl driver expects a reg property explicitly unlike linux.
To align the DT of U-boot with the Linux, reg property is also arrvied
from child GPIO bank nodes when configured under the pinctrl node.

In Linux DT,the pinctrl node acts as parent nodes with all other
gpio banks as child nodes and a single driver in Linux handles both
pinctrl settings and gpio requests.Current U-Boot DT maintains both
pinctrl and gpio nodes as separate nodes and offers two different class
of U-Boot drivers: UCLASS_PINCTRL which handles pin functions and
UCLASS_GPIO which handles gpio requests. In order to align the DT
of U-Boot with the DT of Linux, a hook is been added in the pinctrl
driver to bind the gpio driver with the pinctrl driver so that
when adding gpio nodes as subnodes to pinctrl node (as per the Linux ABI),
the corresponding APIs will be redirected and handled by valid
drivers attached to the pinctrl driver.

This is the last batch of part to push actual support of
OF_UPSTREAM for the mediatek SoC.
The plan is to make the current downstream DTS on part with
upstream implementation so we can permit a gradual transition to
it while we don't cause any regression to any user.
This is to have the same node downstream and upstream.
Mediatek is working hard upstream to also push all the remaining
nodes.
All patch are the final changes after the pinctrl patch
merged previously.

Split imx_pinctrl_set_state() into imx_pinctrl_set_state_common() and
imx_pinctrl_set_state_mmio(). The former does the common configuration
parsing, the later does call imx_pinctrl_set_state_common() and then
does pin configuration using either SCU or MMIO accesses. The SCU part
is going to be moved out in follow up patches.
This is a preparatory patch for follow up pinctrl drivers which
do not use the MMIO accessors, but some other means, like SCU or
otherwise. Those will call the common imx_pinctrl_set_state_common()
function wrapped into some other imx_pinctrl_set_state_*() function,
in a way similar to imx_pinctrl_set_state_mmio() does so for MMIO
accesses.
