drm/i915/display: Enhance iterators for modeset en/disable

Joiners have specific enabling and disabling order dependent on primary
and secondary pipes. This becomes more complex with ultrajoiner where we
have ultrajoiner primary/secondary pipes in addition to bigjoiner
primary/secondary pipes. To unify the approach that works for present
and future joiner cases, use primary and secondary pipe masks to
iterate over pipes.

If joiner is used, derive bigoiner primary and secondary pipe masks
and use following sequences:
Disabling : disable primary pipes followed by secondary pipes,
Enabling: enable secondary pipes followed by primary pipes.

This works well with ultrajoiner too, as ultrajoiner has 2 bigjoiner
primary/secondary pairs (AC, BD).

For non joiner case, enable/disable based on usual pipe order A-D, D-A
respectively.

drm/i915/dp: Fix AUX IO power enabling for eDP PSR

Panel Self Refresh on eDP requires the AUX IO power to be enabled
whenever the output (main link) is enabled. This is required by the
AUX_PHY_WAKE/ML_PHY_LOCK signaling initiated by the HW automatically to
re-enable the main link after it got disabled in power saving states
(see eDP v1.4b, sections 5.1, 6.1.3.3.1.1).

The Panel Replay mode on non-eDP outputs on the other hand is only
supported by keeping the main link active, thus not requiring the above
AUX_PHY_WAKE/ML_PHY_LOCK signaling (eDP v1.4b, section 6.1.3.3.1.2).
Thus enabling the AUX IO power for this case is not required either.

Based on the above enable the AUX IO power only for eDP/PSR outputs.

Bspec: 49274, 53370

v2:
- Add a TODO comment to adjust the requirement for AUX IO based on

Merge tag 'exynos-drm-next-for-v6.12' of git://git./linux/kernel/git/daeinki/drm-exynos into drm-next

Three cleanups
- Drop stale exynos file pattern from MAINTAINERS file
  The old "exynos" directory is removed from MAINTAINERS as Samsung Exynos display bindings have been relocated. This resolves a warning from get_maintainers.pl about no files matching the outdated directory.

- Constify struct exynos_drm_ipp_funcs
  By making struct exynos_drm_ipp_funcs constant, the patch enhances security by moving the structure to a read-only section of memory. This change results in a slight reduction in the data section size.

- Remove unnecessary code
  The function exynos_atomic_commit is removed as it became redundant after a previous update. This cleans up the code and eliminates unused function declarations.

One fixup
- Fix wrong assignment in gsc_bind()
  A double assignment in gsc_bind() was flagged by the cocci tool and corrected to fix an incorrect assignment, addressing a potential issue introduced in a prior commit.

 "A pile of Qualcomm clk driver fixes with two main themes: the alpha
  PLL driver and shared RCGs, and one fix for the Starfive JH7110 SoC.

   - The Alpha PLL clk_ops had multiple problems around setting rates.

     There are a handful of patches here that fix masks and skip
     enabling the clk from set_rate() when the PLL is disabled. The PLLs
     are crucial to operation of the system as almost all frequencies in
     the system are derived from them.

   - Parking shared RCGs at a slow always on clk at registration time
     breaks stuff.

     USB host mode can't handle such a slow frequency and the serial
     console gets all garbled when the UART clk is handed over to the
     kernel. There's a few patches that don't use the shared clk_ops for
     the UART clks and another one to skip parking the USB clk at
     registration time.

   - The Starfive PLL driver used for the CPU was busted causing cpufreq
     to fail because the clk didn't change to a safe parent during
     set_rate().

     The fix is to register a notifier and switch to a safe parent so
     the PLL can change rate in a glitch free manner"

KVM: x86: don't fall through case statements without annotations

clang warns on this because it has an unannotated fall-through between
cases:

   arch/x86/kvm/x86.c:4819:2: error: unannotated fall-through between switch labels [-Werror,-Wimplicit-fallthrough]

and while we could annotate it as a fallthrough, the proper fix is to
just add the break for this case, instead of falling through to the
default case and the break there.

gcc also has that warning, but it looks like gcc only warns for the
cases where they fall through to "real code", rather than to just a
break.  Odd.

   the M extension.
