g: clear reset_counter after update
If the firmware was just updated clear the reset counter before
rebooting. This will ensure that the update can complete even if the TPM
isn't being used.
BUG=chrome-os-partner:56864
BRANCH=none
TEST=Set the reset counter to 7 by running 'rw 0x40000128 1' and
'rw 0x4000012c 7'. Then make sure cr50 can still be updated
