Move RTSM/FVP VExpress variable storage to 256k flash blocks
Change the addresses/sizes of the variable storage areas to use
256k blocks so UEFI is compatible with both the RTSM/FVP models and QEMU.
The VExpress flash has non-uniform block sizes, with most blocks being 256k
and the top 4 blocks being 64k. UEFI has been using these top 64k blocks
for persistent variable storage.
The RTSM models the non-uniform sizes, while QEMU only supports emulating
flash with uniform block sizes which results in the top 256k
(the 4 64k blocks) of flash being unusable for writing in QEMU.
Note that this change will require RTSM flash images to be updated,
as the variable storage has moved. Currently on the A15 model is
supported by QEMU, but all RTSM/FVP models are being changed to keep
the simulation configurations consistent.
