Commit 20f85ef8 ("drm/i915/backlight: use unique backlight device
names") added support for multiple backlight devices on dual panel
systems, but did so with error handling on -EEXIST from
backlight_device_register(). Unfortunately, that triggered a warning in
dmesg all the way down from sysfs_add_file_mode_ns() and
sysfs_warn_dup().

Instead of optimistically always attempting to register with the default
name ("intel_backlight", which we have to retain for backward
compatibility), check if a backlight device with the name exists first,
and, if so, use the card and connector based name.

v2: reworked on top of the patch commit 20f85ef8

MTL introduces a second FBC engine. The two FBC engines can
operate entirely independently, FBC A serving pipe A and
FBC B serving pipe B.

The one place where things might go a bit wrong is the CFB
allocation from stolen. We might have to consider some change
to the allocation strategy to have a better chance of both
engines being able to allocate its CFB. Maybe FBC A should
allocate bottom up and FBC B top down, or something? For the
moment the allocation strategy is DRM_MM_INSERT_BEST for both.

At the moment on DG2 at least loading the DMC firmware's PIPEDMC C and D
programs leads to sporadic unclaimed register accesses while programming
the initial state as described by the firmware's "MMIO init" table. This
will also lead to later unclaimed accesses for unrelated transcoder/pipe
registers backed by the pipe C and D display power wells.

Disabling the PIPEDMC clock gating during initialization - similarly to
Wa_16015201720 fixed this problem in my tests. While pipe A an B
requires the clock gating to be disabled all the time pipe C and D
requires this only while accessing the PIPEDMC registers.

In case GTTMMADDR BAR, let's validate at the beginning of i915

For other BARs, let's validate before first use.

We got a report from Stephen/Michael that the PowerPC build was failing
with the following error:

ld: drivers/gpu/drm/amd/display/dc/dml/display_mode_lib.o uses hard float, drivers/gpu/drm/amd/display/dc/dcn30/dcn30_optc.o uses soft float
ld: failed to merge target specific data of file drivers/gpu/drm/amd/display/dc/dcn30/dcn30_optc.o

This error happened because of the function optc3_set_vrr_m_const. This
function expects a double as a parameter in a code that is not allowed
to have FPU operations. After further investigation, it became clear
that optc3_set_vrr_m_const was never invoked, so we can safely drop this
function and fix the ld issue.
