b896898c73 drm/i915: Tweaked Wa_14010685332 for PCHs used on gen11 platforms 
The WA specifies that we need to toggle a SDE chicken bit on and then
off as the final step in preparation for s0ix entry.

    Bspec: 33450
    Bspec: 8402

However, something is happening after we toggle the bit that causes
the WA to be invalidated. This makes dispcnlunit1_cp_xosc_clkreq
active being already in s0ix state i.e SLP_S0 counter incremented.
Tweaking the Wa_14010685332 by setting the bit on suspend and clearing
it on resume turns down the dispcnlunit1_cp_xosc_clkreq.
B.Spec has Documented this tweaked sequence of WA as an alternative.
Let keep this tweaked WA for Gen11 platforms and keep untweaked WA for
other platforms which never observed this issue.

v2 (MattR):
 - Change the comment on the workaround to give PCH names rather than
   platform names.  Although the bspec is setup to list workarounds by
   platform, the hardware team has confirmed that the actual issue being
   worked around here is something that was introduced back in the
   Cannon Lake PCH and carried forward to subsequent PCH's.
 - Extend the untweaked version of the workaround to include  PCH_CNP as
   well.  Note that since PCH_CNP is used to represent CMP, this will
   apply on CML and some variants of RKL too.
 - Cap the untweaked version of the workaround so that it won't apply to
   "fake" PCH's (i.e., DG1).  The issue we're working around really is
   an issue in the PCH itself, not the South Display, so it shouldn't
   apply when there isn't a real PCH.

v3:
 - use intel_de_rmw(). [Rodrigo]

2ca5a7b85b drm/i915: Handle max_bpc==16 
EDID can declare the maximum supported bpc up to 16,
and apparently there are displays that do so. Currently
we assume 12 bpc is tha max. Fix the assumption and
toss in a MISSING_CASE() for any other value we don't
expect to see.

This fixes modesets with a display with EDID max bpc > 12.
Previously any modeset would just silently fail on platforms
that didn't otherwise limit this via the max_bpc property.
In particular we don't add the max_bpc property to HDMI
ports on gmch platforms, and thus we would see the raw
max_bpc coming from the EDID.

I suppose we could already adjust this to also allow 16bpc,
but seeing as no current platform supports that there is
little point.

b33340e33a drm/meson: dw-hdmi: Ensure that clocks are enabled before touching the TOP registers 
Removing the meson-dw-hdmi module and re-inserting it results in a hang
as the driver writes to HDMITX_TOP_SW_RESET. Similar effects can be seen
when booting with mainline u-boot and using the u-boot provided DT (which
is highly desirable).

The reason for the hang seem to be that the clocks are not always
enabled by the time we enter meson_dw_hdmi_init(). Moving this call
*after* dw_hdmi_probe() ensures that the clocks are enabled.

both triggered by the fact that the HDMI subsystem is still active,
and the DRM removal doesn't result in the connectors being torn down.

Call drm_atomic_helper_shutdown() and component_unbind_all() to safely
tear the module down.

caused by the fact that the RDMA buffer has already been freed,
resulting in meson_rdma_writel_sync() getting a NULL pointer.

Move the afbcd reset and meson_rdma_free calls after the DRM
unregistration is complete so that the teardown can safely complete.

Some media power gates are disabled by default. commit 5d86923060
("drm/i915/tgl: Enable VD HCP/MFX sub-pipe power gating")
tried to enable it, but it duplicated an existent register.
So, the main PG setup sequences ended up overwriting it.

So, let's now merge this to the main PG setup sequence.

v2: (Chris): s/BIT/REG_BIT, remove useless comment,

	     remove rc6 sequence doubt from commit message.
