[RFC PATCH v2 3/8] synquacer: Update for TBBR based new FIP layout

[Masami Hiramatsu]

This changes SPI NOR flash partition layout for TBBR and
also make the U-Boot as position independent executable
again because BL33 is loaded on the memory.

With enabling TBBR, TF-A BL2 loads all BL3x images from
FIP image, and the U-Boot image is added to the FIP image
as BL33, and loaded to memory when boot instead of XIP
on SPI NOR flash. To avoid mixing up with the legacy images,
this new FIP image is stored on unused area (0x600000-) and
the U-Boot env vars are also stored at 0x580000 so that
it will not break existing EDK2 area.
