drm/i915: Add i915.enable_sagv modparam

Browse source

Currently we have no sane way to forcibly disable SAGV, which
makes debugging things a PITA. Manually poking at the pcode
mailbox with it's various SAGV/QGV/PSF formats is no fun,
and likely to be clobbered by the driver anyway.

Let's add a modparam for this.
