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.
