soc/amd/common/psp_verstage: Fix update_boot_region
On SoCs where PSP use A/B recovery layout, PSP expects PSP L2 directory address relative to the start of the SPI ROM. Unfortunately there is nothing in the EFS2 header to help identify such SoCs. Hence add a config item to statically identify such SoCs. Also when PSP uses A/B recovery layout, BIOS L2 directory is an entry in the PSP L2 directory. Hence the address of BIOS L2 directory is not part of EFS2 header. Thankfully PSP is able to identify the BIOS L2 directory itself and does not expect PSP verstage to pass the address. Modify PSP verstage to handle these updates. BUG=b:217414563 TEST=Build Skyrim BIOS image. Ensure that PSP verstage returned the PSP L2 directory as expected.
