drm/xe: Add proper detection of the SR-IOV PF mode
SR-IOV PF mode detection is based on PCI capability as reported by
the PCI dev_is_pf() function and additionally on 'max_vfs' module
parameter which could be also used to disable PF capability even
if SR-IOV PF capability is reported by the hardware.
