If an aux firmware update fails enter recovery with a specific
reason code so we can identify systems that fail.
Also handle the case where the update succeeds and requests a
cold reset of the EC, first clearing the oprom flag if
necessary in order to prevent a second reset.
Unit test was added to check recovery reason for aux firmware
update failure.
BUG=b:74336712
BRANCH=eve
TEST=manual: force update to fail and ensure it goes to recovery
mode, and after successful update check that the option rom flag
is cleared before the EC reset happens.
Unit tests udpated and 'make runtests' passes.
