[RFC 0/2] drm/xe: Support PCIe FLR

PCI subsystem provides callbacks to inform the driver about a request to
do function level reset by user, initiated by writing to sysfs entry
/sys/bus/pci/devices/.../reset. This will allow the driver to handle FLR
without the need to do unbind and rebind as the driver needs to
reinitialize the device afresh post FLR.

we get the below splat but the device has recovered, have executed an
IGT post FLR.
