Defined the plane input csc coefficient registers and macros.
6 registers are used to program a total of 9 coefficients,
added macros to define each of them for all the planes
supporting the feature on pipes. On ICL, bottom 3 planes
have this capability.

v2: Segregated the register macro definition as separate patch
as per Maarten's suggestion.

v3: Removed a redundant 3rd Pipe register definition and
simplified the equally spaced register definition by adding an
offset as per Matt's comment.

v4: No Change

v5: Renamed the register Macro as per Matt's suggestion.

v6: No Change

v7: No Change

v8: No Change

v9: No Change

We're no longer programming any watermarks when we're disabling
a pipe. That means ilk_wm_merge() & co. will keep considering
the any pipe that is getting disabled as still enabled. Thus we
either get no LP1+ watermakrs (ilk-ivb), or we get suboptimal
ones (hsw-bdw).

This seems to have been broken by commit b6b178a7 ("drm/i915:
Calculate ironlake intermediate watermarks correctly, v2."). Before
that we apparently had some difference between the intermediate
and optimal watermarks and so we would program the optiomal ones.
Now intermediate and optimal are identical for disabled pipes
and so we don't program either.

Fix this by programming the intermediate watermarks even for
disabled pipes. We were already doing that for skl+. We'll
leave out gmch platforms for now since those do the merging
in a different manner and should work as is. We'll want to
unify this eventually, but play it safe for now and just put
in a FIXME.

At times 12bpc HDMI cannot be driven due to faulty cables, dongles
level shifters etc. To workaround them we may need to drive the output
at a lower bpc. Currently the user space does not have a way to limit
the bpc. The default bpc to be programmed is decided by the driver and
is run against connector limitations.

Creating a new connector property "max bpc" in order to limit the bpc.
xrandr can make use of this connector property to make sure that bpc does
not exceed the configured value. This property can be used by userspace to
set the bpc.

V2: Initialize max_bpc to satisfy kms_properties
V3: Move the property to drm_connector

The device info offset arrays for unevenly spaced register offsets is
great for widely used registers. However, the palette registers are only
used in one function, i9xx_load_luts_internal(), and only for GMCH
platforms, wasting device info. Replace palette_offsets with _PICK() in
palette register definition.

While the use of _PICK() does not check for pipe C existence, neither
does the current offset array usage, and leads to bogus address when
pipe C is passed to PALETTE() on non-CHV. Using _PICK() at least leads
to a sensible register offset, just non-existing on non-CHV. Either way,
this shouldn't happen anyway.

Remove unused old palette macros while at it.

This patch fixes the naming of the registers:

s/PIPE_DSS_CTL/ICL_PIPE_DSS_CTL

And also fix the hex values to lower case, to match
rest of the definitions.

Manasi noticed this with the patch that was merged.

v2: fix "Fixes" tag.

BIOS can leave the PLL to port mapping enabled, even if the
corresponding encoder is disabled. Disable the port mapping in this
case.

Most of the AUX_CH_CTL flags are concerned with DP AUX transfer
parameters. As opposed to this the flag specifying the thunderbolt vs.
non-thunderbolt mode of the port is not related to AUX transfers at all
(rather it's repurposed to enable either TBT or non-TBT PHY HW blocks).
The programming has to be done before enabling the corresponding AUX
power well, so make it part of the power well code.

v3:
- Use existing enable/disable helpers instead of opencoding. (Jose)
- Fix type of is_tc_tbt to remain a bitfield. (Lucas)
- Add comment describing the is_tc_tbt power well flag. (Lucas)

From ICL onwards the AUX power domain may change dynamically based on
whether a DDI/TypeC port is in thunderbolt or non-thunderbolt mode, so
use a helper function instead of a static field to get the current
domain.

Let's introduce the WA number that is the
cause of having NV12 disabled on both SLK and BXT.

According to Spec:

WA 0870: "Display flickers with NV12 video playback in
Y tiling mode.
WA: Use YUV422 surface format instead of NV12."

First of all I believe this WA as written here was wrong.

Because it is listed on BSpec only for SKL and BXT, exactly
the only 2 platforms skipped here.

But also it is written there that we don't need this WA
anymore:
"This workaround is no longer needed since NV12 support is
dropped for the affected projects in #0870."

SO, let's kill it.
