The VF driver doesn't know which GuC firmware was loaded by the PF
driver and must perform GuC ABI version handshake prior to sending
any other H2G actions to the GuC to submit workloads.

The VF driver also doesn't have access to the fuse registers and
must rely on the runtime info, which includes values of the fuse
registers, that the PF driver is exposing to the VFs.

Add functions to cover that functionality. We will use these
functions in upcoming patches.
