Fix skl_update_scaler_crtc() to deal with different scaling
modes correctly. The current implementation assumes
DRM_MODE_SCALE_FULLSCREEN. Fortunately we don't expose any
border properties currently so the code does actually end
up doing the right thing (assigning a scaler for pfit).
The code does need to be fixed before any borders are
exposed.

Also we have redundant calls to skl_update_scaler_crtc() in
dp/hdmi .compute_config() which can be nuked. They were anyway
called before we had even computed the pfit state so were
basically nonsense. The real call we need to keep is in
intel_crtc_atomic_check().

We only consider crtc_state->enable when initially calculating plane
visibility. Later on we try to override the plane's state to invisible
if the crtc is in DPMS off state (crtc_state->active==false).
Unfortunately the code doing that only updates the plane_state.visible
flag and the crtc_state.active_planes bimask, but forgets to update
some of the other plane bitmasks stored in the crtc_state. Namely
crtc_state.nv12_planes is left set up based on the original visibility
check which makes icl_check_nv12_planes() pick a slave plane for the
flagged plane in the bitmask. Later on we hit the watermark code
which sees a plane with a slave assigned and it then makes the
logical assumption that the master plane must itself be visible.
Since the master's plane_state.visible flag was already cleared
we get a WARN.

Fix the problem by clearing all the plane bitmasks for DPMS off.
This is more or less the wrong approach and instead we should
calculate all the plane related state purely based crtc_state->enable
(to guarantee that the subsequent DPMS on can't fail). However in
the past we definitely had some roadblocks to making that happen.
Not sure how many are left these days, but let's stick to the current
approach since it's a much simpler fix to the immediate problem
(the WARN).

As a disabled pipe in pipe_mask is not having a valid intel crtc,
driver wrongly populates the possible_crtcs mask while initializing
the plane for a CRTC. Fixing up the plane possible_crtcs mask.

changes since RFC:
- Simplify the possible_crtcs initialization. [Ville]
v2:
- Removed the unnecessary stack garbage possible_crtcs to
  drm_universal_plane_init. [Ville]
v3:
- Combine the intel_crtc assignment and declaration. [Ville]
v4:
- Fix possible_crtcs abused bits from
  intel_{primary,curosr,sprite}_plane_create(). [Ville]

Looks like the pipe rounding mode bit has moved from PIPE_CHICKEN to
PIPE_MISC on tgl. Frob the new location.

Bspec does still document the old bits as well, so I left the code
for them as is until we get clarification from the hw folks on
whether the old bits still do something useful.

The #include has been splattered all over the place, but there are
precious few places, all .c files, that actually need it.

v2: remove leftover double newlines
