VBE needs to load different images from a FIT depending on the xPL phase
in use. The IH_PHASE value is used to select the image to load.
Add the required logic to handle this. For compatibility with the
SPL-loader driver, fill out a struct spl_image_info with the details
needed to boot the next phase.
This is good enough for VBE-simple but ABrec will need the full set of
bootstd features. So add a USE_BOOTMETH define to control this.

Add FDT support so that this can be copied down in memory after loading
and made available to the new image.

This is fairly easy to use. The SPL loader sets up some fields in the
spl_image_info struct and calls spl_reloc_prepare(). When SPL is ready
to do the jump it must call spl_reloc_jump() instead of jump_to_image().
Add this logic.

When one xPL phase wants to jump to the next, the next phase must be
loaded into its required address. This means that the TEXT_BASE for the
two phases must be different and there cannot be any memory overlap
between the code used by the two phases. It also can mean that phases
need to be moved around to accommodate any size growth.
Having two xPL phases in SRAM at the same time can be tricky if SRAM
is limited, which it often is. It would be better if the second phase
could be loaded somewhere else, then decompressed into place over the
top of the first phase.
Introduce a relocating jump for xPL to support this. This selects a
suitable place to load the (typically compressed) next phase, copies
some decompression code out of the first phase, then jumps to this code
to decompress and start the next phase.
This feature makes it much easier to support Verified Boot for Embedded
(VBE) on RK3399 boards, which have 192KB of SRAM.

This function will be used by the relocating jumper too, so add a
typedef to the header file to avoid mismatches.

In many cases the FIT includes a devicetree. Add support for loading
this into a suitable place in memory.

In some cases only the 'loadable' property is present in the FIT.
Handle this by loading the first such image.

There is no guarantee that an FIT image starts on a block boundary. When
it doesn't, the image starts part-way through the first block.
Add logic to detect this and copy the image down into place.

At present the VBE implementation is limited to sandbox only. Adjust the
call to fit_image_load() to remove this limitation.

It is convenient to use TEXT_BASE as a place to hold the FIT header, but
this does not work in VPL, since SDRAM is not inited yet.
Allocate the memory instead. Ensure the size is aligned to the media
block-size so that it can be read in directly. Improve the
error-checking for blk_read() and add some more debugging.
Keep the existing TEXT_BASE mechanism in sandbox to avoid an
'Exec format error' when trying to run the image.

Loading a FIT is useful for other VBE methods, such as ABrec. Create a
new function to handling reading it.

VBE is currently quite careful with function arguments because it is
used in VPL which cannot be updated after manufacture. Bugs can cause
security holes.
Unfortunately this adds to code size.
In several cases we are reading values from a devicetree which is part
of U-Boot (or at least VPL) and so known to be good. Also, in several
places, getting bad values does not matter.
So change a few checks to assert() to reduce code size.

There is no point in checking the pre_reloc flag, since devices not
marked as pre-reloc will not have been bound, so won't exist yet.
There doesn't seem to be any point in checking if the device has a
valid devicetree node either, so drop that too.

This releases the DP configuration from reset early on during the boot process
for K26 SOM. It will also avoid the boot hang situation should any attempt be
made to configure the DP registers while it is still in reset.

The main reason for this change is that upstream QEMU has no multiboot
register implemented that's why access to it fails which ends up in CI
failure for our target.
That's why in JTAG bootmode returns 0 which is correct behaviour because
multiboot register is not used in this mode and value should be ignored and
as a side effect it is also fixing CI/Qemu issue.
Also move versal_get_bootmode() to avoid function declaration.
