mb/google/brya/variants/volmar: Add firmware config field for FPMCU
The fingerprint(FP) feature is only for volmar,and it's not for zavala.
Add FPMCU_MASK field in fw_config to disable the FP function for
zavala, and reserve FP function for shipped volmar.
Define the value as following:
field FPMCU_MASK 10
option FPMCU_ENABLED 0
option FPMCU_DISABLED 1
end
BUG=b:250807253
TEST=build firmware and verify the fp function in volmar DUT.
write `disable=1` and 'enable=0' in FPCMU_MASK field.
check the fp function and run `ectool --name cros_fp version`
It works as expected.
