meta-zaius: avsbus-control: Add VOUT_COMMAND workaround
When switching voltage regulator modules (VRM) on Zaius to AVSBus-
controlled operation, the initial output voltage should be copied from
the PMBus VOUT_COMMAND register. However, the Intersil VRM does not
perform the copy following the first switch from PMBus- to AVSBus-
controlled operation.
Add a workaround to the AVSBus enable step that writes the value of
VOUT_COMMAND to itself in order to initialize the otherwise BMC
inaccessible AVSBus voltage setpoint.
