drm/xe: Enable Boot Survivability mode

Browse source

Enable boot survivability mode if pcode initialization fails and
if boot status indicates a failure. In this mode, drm card is not
exposed and driver probe returns success after loading the bare minimum
to allow firmware to be flashed via mei.

v2: abstract survivability mode variable
    add BMG check inside function (Jani, Rodrigo)

v3: return -EBUSY during system suspend (Anshuman)
    check survivability mode in pci probe only
    on error
