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.
