I just gave a try to this new iteration and it's apparently failing to
enable PXP on a machine with this pciID : 0x9a68.

PXP (Protected Xe Path) is an i915 component, available on

I'm taking over this series from Sean. I've significantly reworked the
code since his last revisioni [1], including a different patch split, so
I've reset the series revision count. I believe I've addressed most of
the pending comments, but please point out aything I've missed.
Still RFC for 2 reasons:
- mutex usage needs a bit more reworking
- very lightly tested
