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.

Add a size limit for VPL, to match those for SPL and TPL

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.
