firmware: allocate nvram bit for diagnostic mode
This change allocates a bit in the nvram that will be used
in a later change to tell the firmware whether to detour
to diagnostic mode during boot.
BUG=b:124358784
BRANCH=None
TEST=Local build and ran "make runtests". Verified with a later
change that the nvram bit takes effect as expected.
