Disable voltage override causing CFAM error
During investigation of openbmc/openbmc#2191 it was determined
that the change done in openbmc/openbmc#1958 was causing
the CFAM operations to the second processor to fail. Disable
this voltage override until root cause of the CFAM fail
is determined.
Resolves openbmc/openbmc#2191
