drm/amd/display: Allow backlight to go below `AMDGPU_DM_DEFAULT_MIN_BACKLIGHT`
[ Upstream commit
87d749a6aab73d8069d0345afaa98297816cb220 ]
The issue with panel power savings compatibility below
`AMDGPU_DM_DEFAULT_MIN_BACKLIGHT` happens at
`AMDGPU_DM_DEFAULT_MIN_BACKLIGHT` as well.
That issue will be fixed separately, so don't prevent the backlight
brightness from going that low.
