Vadim Bendebury cdd2c95284 g: protect flash operations ...

Flash operations in do_flash_op() involve waiting polling for the chip
to complete the operation. If a concurrent operation is started while
another operation is in progress, flash gets confused and locks up.

Let's add a mutex to ensure that flash operation runs to completion
before another operation starts.

BRANCH=cr50
BUG=b:67651754
TEST=multiple times ran firmware update while the device was coming up
     and saving TPM status in NVMEM. Observed no failures.
