soc/amd/picasso: If using VBOOT, skip the APOB_NV region for RO
When booting from the RO region of a VBOOT enabled ROM, there shouldn't be a reliance on anything outside of the RO section. This includes the APOB_NV region (similar to the MRC cache region). By skipping the region when setting up the BIOS Directory table, the PSP won't try to use the region when booting. The APOB_NV region is still used for the VBOOT RW sections. BUG=b:158363448 TEST=Build RO with no APOB_NV region. Dump the BDT and verify that it's not in RO, but is in RW_A & RW_B. Boot into recovery.
