LPDDR3 and LPDDR4 support, needed by new boards. The sun8i-emac

replaced the SPL, and required to equip the U-Boot (proper) binary with
a vendor specific header to be recognised as a valid boot0 payload.

Some SoCs of the H616 family use a die variant, that puts some CPU power

of two instances of the same board, using different die revisions of the
otherwise same H313 SoC. We need to write to a register in that block
*very* early in the SPL boot, to switch the core to AArch64.
Since the devices are otherwise indistinguishable, let the SPL code read
that die variant and use the respective RVBAR address based on that.
That is a bit tricky, since we need to do that in hand-coded AArch32
machine language, shared by all 64-bit SoCs. To avoid build dependencies
in this mess, we always provide two addresses to choose from, and just
give identical values for all other SoCs. This allows the same code to
run on all 64-bit SoCs, and controls this switch behaviour purely from
