mach-k3: am62a7_init: Avoid HSM SRAM access from A53 SPL/U-Boot
Starting with v08.05.01 TIFS, HSM SRAM access is restricted to only the
DM firmware and SMS cores meaning the A53 SPL and U-Boot will no longer
be able to access these parts of SRAM.
Unfortunately there are two data structures located in the HSM SRAM the
A53's boot-loaders will need and now must be relocated by the R5 SPL.
1. The boot index from ROM, indicating whether ROM booted from the
primary vs backup boot media.
2. And the Board EEPROM data scratch pad.
The EXTENDED BOOT INFO, indicating which images ROM loaded is not needed
by the A53 SPL and is now limited to the R5 SPL.
