feasible baseline for topic branches.

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.

This workaround is specific for a particular panel on Google
chromebook project. When user space daemon enter idle state.
It request adjust brightness to 0, turn backlight_enable signal
off and keep eDP main link active.
On general LCD, this behavior might not be a problem.
But on this panel, its tcon would expect source to execute
full eDP power off sequence after drop backlight_enable signal.
Without eDP power off sequence. Even source try to turn
backlight_enable signal on and restore proper brightness level.
This panel is not able to light on again.
This WA ignored the request from user space daemon to disable
backlight_enable signal and keep it on always. When user space
request kernel to turn eDP display off, kernel driver still
can control backlight_enable signal properly. It would not
impact standard eDP power off sequence.
v2: 1. modify the quirk name and debug messages.
2. unregister backlight.power callback for specific device.
v3: 1. modify debug output messages.
2. use DMI_EXACT_MATCH instead of DMI_MATCH.

This patch adds Pipe A plumbing to the already
existing parsing and loading functions which is
taken care of in the prep patches. Adding MAX_DMC_FW
to keep track for both Main and Pipe A DMC while loading
the respective blobs.
Also adding present field in dmc_info.
s/find_dmc_fw_offset/csr_set_dmc_fw_offset. While at it add
fw_info_matches_stepping() helper. CSR_PROGRAM() should now
take the starting address of the particular blob (Main or Pipe)
and not hardcode it.
v2: Add dmc_offset and start_mmioaddr fields for dmc_info struct.
v3: Add a missing corner cases of stepping-substepping combination in
fw_info_matches_stepping() helper.
v4: Add macro for start_mmioaddr for V1 package. Simplify code
in dmc_set_fw_offset (Lucas)

Disconnect TypeC PHYs during system suspend and shutdown, even with the
corresponding TypeC sink still plugged to its connector, since leaving
the PHY connected causes havoc at least during system resume in the
presence of an Nvidia card.
Note that this will only make a difference in the TypeC DP alternate
mode, since in Thunderbolt alternate mode the PHY is never owned by the
display engine and there is no notion of PHY ownership in legacy mode
(the display engine being the only possible owner in that mode and the
TypeC subsystem not having anything to do with the port in that case).

When pipe A is disabled and MIPI DSI is enabled on pipe B,
the AMT KVMR feature will incorrectly see pipe A as enabled.
Set 0x42080 bit 23=1 before enabling DSI on pipe B and leave
it set while DSI is enabled on pipe B. No impact to setting
it all the time.
Changes since V5:
- Added reviewed-by
- Removed redundant braces and debug message format - Imre
Changes since V4:
- Modified function comment Wa_<number>:icl,jsl,ehl - Lucas
- Modified debug message in sync state - Imre
Changes since V3:
- More meaningful name to workaround - Imre
- Remove boolean check clear flag
- Add WA_verify hook in dsi sync_state
Changes since V2:
- Used REG_BIT, ignored pipe A and used sw state check - Jani
- Made function wrapper - Jani
Changes since V1:
- ./dim checkpatch errors addressed
