VPL has the same needs as TPL in situations where the stack is at the
top of SRAM. Add an option for this and implement it for arm

Allow a linker script to be provided for VPL as it is for other U-Boot
phases.

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.

The VPL phase may want to use the smaller malloc() implementation, so
add an option for this.

This reverts commit 1fdf53ace13f745fe8ad4d2d4e79eed98088d555, reversing
changes made to e5aef1bbf11412eebd4c242b46adff5301353c30.
I had missed that this caused too much size growth on rcar3_salvator-x.

Enable the various features needed in VPL, by adding Kconfig options.
Update the defconfig for sandbox_vpl so that the build for each phase
includes what is needed. Drop LZMA for now and make sure partition support
is omitted in SPL, since it is not needed.

Since commit 2a7360666871 ("serial: Rename SERIAL_SUPPORT to SERIAL")
SPL_SERIAL_SUPPORT is named SPL_SERIAL. So let's update the comment to
point to the correct Kconfig option in the comment of VPL_SERIAL.

The i.MX8M boards use partially specified binman images which have an
SPL entry without a U-Boot entry. This would normally cause an error due
to the 'u_boot_any' binman symbols declared by BINMAN_UBOOT_SYMBOLS
requiring a U-Boot-like entry in the same image as the SPL.
However, a problem in the ARMv8 __image_copy_start symbol definition
effectively disables binman from attempting to write any symbols at all,
so everything appears to work fine until runtime. A future patch fixes
the issue in the linker scripts, which lets binman fill in the symbols,
which would result in the build error described above.
Explicitly disable the 'u_boot_any' symbols for i.MX8M boards. They are
already effectively unusable, and they are incompatible with the boards'
current binman image descriptions.

The SPL code declares binman symbols for U-Boot phases depending on
CONFIG_IS_ENABLED(BINMAN_UBOOT_SYMBOLS). This config exists for SPL and
TPL, also add a version for VPL.

- Move all PowerPC (and some shared with Layerscape) options to
common/spl/Kconfig.nxp
- Move all other TPL related options to common/spl/Kconfig.tpl
- Move all VPL related options to common/spl/Kconfig.vpl
This makes the whole of common/spl/Kconfig slightly more readable.
