Till DISPLAY12 the PIPE_MISC bits 5-7 are used to set the
Dithering BPC, with valid values of 6, 8, 10 BPC.
For ADLP+ these bits are used to set the PORT OUTPUT BPC, with valid
values of: 6, 8, 10, 12 BPC, and need to be programmed whether
dithering is enabled or not.
This patch:
-corrects the bits 5-7 for PIPE MISC register for 12 BPC.
-renames the bits and mask to have generic names for these bits for
dithering bpc and port output bpc.

UAPI Changes:
- Add I915_MMAP_OFFSET_FIXED
On devices with local memory `I915_MMAP_OFFSET_FIXED` is the only valid
type. On devices without local memory, this caching mode is invalid.
As caching mode when specifying `I915_MMAP_OFFSET_FIXED`, WC or WB will
be used, depending on the object placement on creation. WB will be used
when the object can only exist in system memory, WC otherwise.
Userspace: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/11888
- Reinstate the mmap ioctl for (already released) integrated Gen12 platforms
Rationale: Otherwise media driver breaks eg. for ADL-P. Long term goal is
still to sunset the IOCTL even for integrated and require using mmap_offset.
- Reject caching/set_domain IOCTLs on discrete
Expected to become immutable property of the BO
- Disallow changing context parameters after first use on Gen12 and earlier
- Require setting context parameters at creation on platforms after Gen12
Rationale (for both): Allow less dynamic changes to the context to simplify
the implementation and avoid user shooting theirselves in the foot.
- Drop I915_CONTEXT_PARAM_RINGSIZE
Userspace PR for compute-driver has not been merged
- Drop I915_CONTEXT_PARAM_NO_ZEROMAP
Userspace PR for libdrm / Beignet was never landed
- Drop CONTEXT_CLONE API
Userspace PR for Mesa was never landed
- Drop getparam support for I915_CONTEXT_PARAM_ENGINES
Only existed for symmetry wrt. setparam, never used.
- Disallow bonding of virtual engines
Drop the prep work, no hardware has been released needing it.
- (Implicit) Disable gpu relocations
Media userspace was the last userspace to still use them. They
have converted so performance can be regained with an update.

CI test results/further experiments show that the workaround added in
commit 573d7ce4f6 ("drm/i915/adlp: Add workaround to disable CMTG clock gating")
can be applied only while DPLL0 is enabled. If it's disabled the
TRANS_CMTG_CHICKEN register is not accessible. Accordingly move the WA
to DPLL0 HW state sanitization and enabling.
This fixes an issue where the WA won't get applied (and a WARN is thrown
due to an unexpected value in TRANS_CMTG_CHICKEN) if the driver is
loaded without DPLL0 being enabled: booting without BIOS enabling an
output with this PLL, or reloading the driver.
While at it also add a debug print for the unexpected register value.

The driver doesn't depend atm on the common mode timing generator
functionality (it would be used for some power saving feature and panel
timing synchronization), however DMC will corrupt the CMTG registers
across DC5 entry/exit sequences unless the CMTG clock gating is
disabled. This in turn can lead to at least the DPLL0/1 configuration
getting stuck at their last state, which means we can't reprogram them
to a new config.
Add the corresponding Bspec workaround to prevent the above.

Not following it did not caused any problems up to Alderlake-P but

Currently when we do the HW state readout, we dont set the shared dpll to NULL
for the bigjoiner slave which should not have a DPLL assigned. So it has
some garbage while the HW state readout is NULL. So explicitly reset
the shared dpll for bigjoiner slave pipe.

Add a single point of truth for figuring out the primary/secondary crtc
for bigjoiner instead of duplicating the magic pipe +/- 1 in multiple
places.
Also fix the pipe validity checks to properly take non-contiguous pipes
into account. The current checks may theoretically overflow
i915->pipe_to_crtc_mapping[pipe], albeit with a warning, due to fused
off pipes, as INTEL_NUM_PIPES() returns the actual number of pipes on
the platform, and the check is for INTEL_NUM_PIPES() == pipe + 1.
Prefer primary/secondary terminology going forward.
v2:
- Improved abstractions for pipe validity etc.

Just pass the full atomic state+crtc to the pre-skl watermark
functions, and clean up the types/variable names around the area.
Note that having both .compute_pipe_wm() and .compute_intermediate_wm()
is entirely redundant now. We could unify them to a single vfunc.
But let's do this one step at a time.

When PSR is enabled it handles DP_SDP_VSC, changing revision and all
the other fields as necessary.
It can also enabled and disable this SDP as needed without a full
modeset.
So here masking DP_SDP_VSC bit when previous and future state PSR
enabled, it will still be checked when comparing the asked state
to what was programmed to hardware.

Commit 78b772e1a0 ("drm/i915/display: Fill PSR state during hardware
configuration read out") is not allowing fastsets to happen when PSR
states changes but PSR is a feature that can be enabled and disabled
during fastsets.
So here moving the PSR pipe conf checks to a block that is only
executed when checking if HW state matches with requested state, not
during the phase where it checks if fastset is possible or not.
There still a state mismatch not allowing fastsets between states
turning off or on PSR because of crtc_state->infoframes.enable
BIT(DP_SDP_VSC) but at least for now it will allow a fastset between
PSR1 <-> PSR2, that is a case heavilly used by CI due to pipe CRC not
work with PSR2, but the remaning issue will be fixed in a future patch.
