The LP refers to 'low priority' as opposed to the high priority
ring on gen2/3. So lets constrain its use to the code of that era.
Unfortunately we can't yet completely remove the associated
macros from common headers and shove them into i915_dma.c to
the other dri1 legacy support code, a few cleanups are still
missing for that.

I've missed this one.
v2: Chris Wilson noticed another register.
v3: Color choice improvements.

The specs recommend that this bit be set on PineView. No reason is
given, but it sounds like a powersaving bit that we should expect the
BIOS to be setting...
v2: Rebase on top of _MASKED_ENABLE_BIT

Copy&pasted from the vlv setup code. According to docs, we need that
on ivb, too.
v2: Use new masked bit handling macros.

... and put them to so good use.
Note that there's functional change in vlv clock gating code, we now
no longer spuriously read back the current value of the bit. According
to Bspec the high bits should always read zero, so ORing this in
should have no effect.

This got lost in the intel_pm.c move.

This adds intel_pm routine for generic power-related infrastructure
initialization.
v2: now that all the platform-specific stuff is initialized in one place, we
can also add back the static definitions to platform-specific functions which
we abstract now.

This moves the clock gating-related functions into intel_pm module.
Also, please note that we do change the function type from static to
non-static in this patch for the move, to prevent breaking bisecting with
non-working intermediate commit. Those are returned back to static form in
the following patch which setups a generic PM initialization function,
which was split into a different one to simplify review.
v2: rebase on top of latest drm-intel-next-queued to incorporate all the
changes that went there meanwhile.

This moves DRPS, RPS and RC6-related functionality into intel_pm module.
It also removes the linux/cpufreq.h include from intel_display, as its
only user was the GPU turbo-related functionality in Gen6+ code path.
v2: rebase on top of latest drm-intel-next-queued adding the bits that
shifted around since the last patch.
