drm/xe/pf: Add FLR_PREPARE state to VF control flow
Our xe-vfio-pci component relies on the confirmation from the PF
that VF FLR processing has finished, but due to the notification
latency on the HW/FW side, PF might be unaware yet of the already
triggered VF FLR.
Update VF state machine with new FLR_PREPARE state that indicate
imminent VF FLR notification and treat that as a begin of the FLR
sequence. Also introduce function that xe-vfio-pci should call to
guarantee correct synchronization.
v2: move PREPARE into WIP, update commit msg (Michal)
