Add reset_reset() and reset_reset_bulk() functions to the reset
controller API. These functions assert and then deassert reset signals
in a single call, providing a convenient way to pulse/toggle a reset
line.
This mimics the Linux kernel's reset_control_reset() and
reset_control_bulk_reset() APIs. The new functions are useful for
drivers that need to cycle a reset line during initialization or
error recovery but with also passing delay parameter.
If a driver implements the rst_reset op, it will be called directly
with the delay parameter. Otherwise, the reset core performs
reset_assert(), optional udelay(), and reset_deassert() as fallback.

The old check accepted day 0 as well as Feb 29th in non-leap years.
With this change, both day and month 0 are rejected, and the local day
limit logic is now handled by rtc_month_days(), which correctly accounts
for month length and leap years.
In the 'MMDDhhmm' format case, tm_year is not initialized by mk_date().
The leap-year calculation in rtc_month_days() therefore depends on the
value provided by the caller, which do_date() does, via dm_rtc_get().
This is pre-existing behaviour, but is now made more explicit.

When commit 1d7993d1d0
("clk: Port Linux common clock framework [CCF] for imx6q to U-boot (tag: v5.1.12)")
introduced the parts of Linux Common Clock Framework, it was done for i.MX6
only and even had "depends on SPL_CLK_IMX6Q" conditions. Since commit
ccab06689a ("clk: imx: expose CCF entry for all") the framework can be
reused with SoCs of other vendors (say, TI), but NXP SoC-specific code is
still being build. It is especially problematic for size-constrained SPL
images on TI AM62x.
Make the build of the i.MX/RTxxxx code not only dependent on
CONFIG_$(PHASE_)CLK_CCF, but also on CONFIG_MACH_IMX options which shall
cover the i.MX platform users.
This saves 2264 bytes on 32-bit ARM platforms [using CCF].

The variable `pend_tab_total_sz` is calculated using the macro

However, `lpi_id_bits` is initialized later in the function based on
the GICD_TYPER register. This results in `pend_tab_total_sz` being
calculated with an uninitialized `lpi_id_bits` value (0), This leads
to the LPI pending tables being mapped with an incorrect size.
