drm/amd/display: Scale custom brightness curve from full range

Custom brightness curves use an 8-bit input signal. After exporting the
full PWM range to userspace, the curve normalizer still divides requests
by the physical PWM span. On panels with a nonzero minimum PWM level,
this can produce a curve input greater than 255 and send an invalid
backlight level to DC.

Scale the userspace [0..max] range to the curve's [0..255] range
instead. This retains the full advertised range and keeps the reverse
readback conversion unchanged.

drm/amd/display: Force PWM backlight on Lenovo Legion 5 15ARH05

The Lenovo Legion 5 15ARH05 (Renoir) ships a BOE 0x08DF eDP panel that
advertises AUX/DPCD backlight control, so amdgpu's automatic detection
(amdgpu_backlight == -1) selects AUX. On this panel the AUX backlight
path has no effect: brightness writes are accepted but the panel level
never changes, the display is stuck at a fixed brightness and
max_brightness is reported as a bogus 511000. As a result neither the
desktop brightness slider nor the brightness hotkeys do anything.

Forcing PWM backlight (amdgpu.backlight=0) restores working control:
max_brightness becomes 65535 and the level tracks writes. This has long
been applied by users as a manual kernel-parameter workaround.

Extend the generic panel backlight quirk with a force_pwm flag, add an
entry for the Legion 5 15ARH05 / BOE 0x08DF panel, and have amdgpu
disable AUX backlight (use PWM) when the quirk matches and the user
lets the driver auto-select the backlight type.

invalid text, and out-of-range input. show() writes through a page-backed
buffer because sysfs_emit() requires one.

[WHAT]
Add KUnit coverage for the backlight level write path in
amdgpu_dm_backlight.c.

Tests cover stream lookup hit/miss, the connector-off and no-stream early
returns, and the AUX/PWM/idle-reallow programming branches. The DC
programming calls stay safe by injecting a NULL power module and keeping
idle optimizations a no-op via disable_idle_power_optimizations.

drm/amd/display: Fix backlight max_brightness to match exported range

[Why]
FWTS autobrightness fails on eDP panels because actual_brightness can
read higher than the advertised max_brightness (e.g. 63576 vs 62451).

The conversion helpers expose the firmware PWM range to userspace as
[0..max]. But max_brightness is advertised as (max - min), which is
smaller. So reading the level can return a value above max_brightness.

This regressed in commit 4b61b8a39051 ("drm/amd/display: Add debugging
message for brightness caps"), which changed max_brightness to
(max - min) and undid commit 8dbd72cb7900 ("drm/amd/display: Export full
brightness range to userspace").

[How]
Advertise max_brightness as max, and scale the initial AC/DC brightness
against max too. Update the KUnit expectations to match.

Add KUnit coverage for both new helpers. Keep the runtime
power_supply_is_system_supplied() call at the caller so
the helpers remain pure and deterministic under test.
