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.
