soc/amd/mendocino: Do not load MP2 Firmware when in RO
Currently MP2 Firmware is not built into RO firmware section but the
soft fuse bit to disable MP2 firmware loading is not set. This causes
the device to boot loop during recovery mode. Set the bit to disable MP2
firmware loading in RO.
BUG=b:259554520
TEST=Build and boot to OS in Skyrim under both normal and recovery
modes.
