The function radeon_resume_kms() acquires the console lock. It is
inconsistent, as it depends on the notify_client argument. That
lock then covers a number of suspend operations that are unrelated
to the console.
Remove the calls to console_lock() and console_unlock() from the
radeon function. The console lock is only required by DRM's fbdev
emulation, which acquires it as necessary.
Also fixes a possible circular dependency between the console lock
and the client-list mutex, where the mutex is supposed to be taken
first.

In DCN401 pre-blending degamma LUT isn't affecting cursor as in previous
DCN version. As this is not the behavior close to what is expected for
CRTC degamma LUT, disable CRTC degamma LUT property in this HW.
Link: https://gitlab.freedesktop.org/drm/amd/-/issues/4176

When enabling HDR on KDE, it takes the first CRTC 1D LUT available and
apply a color transformation (Gamma 2.2 -> PQ). AMD driver usually
advertises a CRTC degamma LUT as the first CRTC 1D LUT, but it's
actually applied pre-blending. In previous HW version, it seems to work
fine because the 1D LUT was applied to cursor too, but DCN401 presents a
different behavior and the 1D LUT isn't affecting the hardware cursor.
To address the wrong gamma on cursor with HDR (see the link), I came up
with this patch that disables CRTC degamma LUT in this hw, since it
presents a different behavior than others. With this KDE sees CRTC
regamma LUT as the first post-blending 1D LUT available. This is
actually more consistent with AMD color pipeline. It was tested by the
reporter, since I don't have the HW available for local testing and
debugging.

SmartMux is a mechanism to switch the GPU being used for scanout in a
hybrid configuration. This is used for devices with an eDP and two GPUs.
This is only valid when the system has a physical switch (Multiplexer)
in the board to switch between the two GPUs.
When a graphically intensive workload like a game is being run, the
system can be switch the active display to the dGPU, so that we can
avoid copying the buffer from dGPU to APU for scanout. This helps with
latency and FPS. When power consumption is preferred, the system can be
switched to the APU.
