Add Bus class to reset OCC bus driver
For some systems, the OCC is accessed over the SBEFIFO, acting as a bus.
If the SBE experiences a failure, the SBEFIFO driver is unable to
recover. Therefore, the OCC control application must force a reset of
the SBEFIFO driver when the OCC goes active.
Add a Bus class and reset method to unbind and bind the appropriate
SBEFIFO devices when the OCC devices are bound.
Testing: Powered on the system successfully. Injected SBE error through
a putscom. Without this fix, I intermittently saw SBEFIFO errors on the
BMC after the injection. With the fix, I saw no errors despite ~20
iterations.
Resolves openbmc/openbmc#3156
