fw_config: Convert fw_config to a 64-bit field
We all knew this was coming, 32 bits is never enough. Doing this early so that it doesn't affect too much code yet. Take care of every usage of fw_config throughout the codebase so the conversion is all done at once. BUG=b:169668368 TEST=Hacked up this code to OR 0x1_000_0000 with CBI-sourced FW_CONFIG and verify the console print contained that bit.
