Revision checks are almost always accompanied by a platform check. (The
exceptions are platform specific code.) Add helpers to check for a
platform and a revision range: IS_SKL_REVID() and IS_BXT_REVID(). In
most places this simplifies and clarifies the code. It will be obvious
that revid macros are used for the correct platform.

This should make it easier to find all the revision checks for
workarounds for each platform, and make it easier to remove them once we
drop support for early hardware revisions.

This should also make it easier to differentiate between Skylake and
Kabylake revision checks when Kabylake support is added.

Just pull the info out of the state structures rather than staging
it in an additional set of structures.  To make this more
straightforward, we change the signature of several internal WM
functions to take the crtc state as a parameter.

v2:
 - Don't forget to skip cursor planes on a loop in the DDB allocation
   function to match original behavior.  (Ander)
 - Change a use of intel_crtc->active to cstate->active.  They should
   be identical, but it's better to be consistent.  (Ander)
 - Rework more function signatures to pass states rather than crtc for
   consistency. (Ander)

v3:
  - Add missing "+ 1" to skl_wm_plane_id()'s 'overlay' case. (Maarten)
  - Packed formats should pass '0' to drm_format_plane_cpp(), not 1.
    (Maarten)
  - Drop unwanted WARN_ON() for disabled planes when calculating data
    rate for SKL.  (Maarten)

v4:
 - Don't include cursor plane in total relative data rate calculation;
   we've already handled the cursor allocation earlier.
 - Fix 'bytes_per_pixel' calculation braindamage.  Somehow I hardcoded
   the NV12 format as a parameter rather than the actual
   fb->pixel_format, and even then still managed to get the format plane
   wrong.  (Ville)
 - Use plane->state->fb rather than plane->fb in
   skl_allocate_pipe_ddb(); the plane->fb pointer isn't updated until
   after we've done our watermark recalculation, so it has stale
   values.  (Bob Paauwe)

Since the beginning we have conflated the size of the global GTT with
that of the per-process context sizes. In recent times (gen8+), those
are no longer the same where the global GTT is limited to 2/4GiB but the
per-process GTT may be anything up to 256TiB. Userspace knows nothing of
this discrepancy and outside of one or two hacks, uses the getaperture
ioctl to determine the maximum size it can use. Let's leave that as
reporting the global GTT and use the context reporting method to
describe the per-process value (which naturally fallsback to reporting
the aliasing or global on older platforms, so userspace can always use
this method where available).

Mmio register access after dc6/dc5 entry is not allowed when

so enabling dc6 as the last call in suspend flow.

Addtional note from Imre:

Currently we keep DC6 enabled during modesets and DPAUX transfers, which
is not allowed according to the specification. This can lead at least to
PLL locking failures, DPAUX timeouts and prevent deeper package power
states (PC9/10). Fix this for now by enabling DC6 only when we know the
above events (modeset, DPAUX) can't happen.

Some registers are, naturally, lost in gpu reset/suspend cycle.
And some registers, for example in display domain, are not subject
to gpu reset so they retain their contents.

As hang recovery triggers a reset, recoverable gpu hang can currently
flush out essential workarounds and cause havoc later on.

When register GEN8_GARBNTL is missing the WaEnableGapsTsvCreditFix:skl,
it can cause random system hangs [1]. This workaround was added in:
commit 245d9667 ("drm/i915:skl: Add WaEnableGapsTsvCreditFix")
But another set of system hangs were observed and the failure pattern
indicated that there was random gpu hang preceding the system hang [2].
This lead to the realization that we lose this workaround and BDW_SCRATCH1
on reset.

Add these workarounds setup in display init to skl/bxt ring init
where LRI workarounds are also setup. This way their setup is not
dependent on display side init.
