drm/i915: Add Wa_14010733141

The WA requires the following procedure for VDBox SFC reset:

If (MFX-SFC usage is 1) {
	1.Issue a MFX-SFC forced lock
	2.Wait for MFX-SFC forced lock ack
	3.Check the MFX-SFC usage bit
	If (MFX-SFC usage bit is 1)
		Reset VDBOX and SFC
	else
		Reset VDBOX
	Release the force lock MFX-SFC
}
else if(HCP+SFC usage is 1) {
	1.Issue a VE-SFC forced lock
	2.Wait for SFC forced lock ack
	3.Check the VE-SFC usage bit
	If (VE-SFC usage bit is 1)
		Reset VDBOX
	else
		Reset VDBOX and SFC
	Release the force lock VE-SFC.
}
else
	Reset VDBOX

- Restructure: the changes to the original code flow should stay
  relatively minimal; we only need to do an extra HCP check after the
  usual VD-MFX check and, if true, switch the register/bit we're
  performing the lock on.(MattR)

v2:
- Assign unlock mask using paired_engine->mask instead of using
  BIT(paired_vecs->id). (Daniele)
