drm/amd/display: Correctly restore user_level
[Why]
BL1_PWM_USER_LEVEL is meant for the user brightness level setting from
OS. However, we update it along with other ABM levels to the real PWM
value which could be ABMed.
[How]
Driver to cache and restore the user brightness level setting so that
DMUB can retrieve the last user setting in ABM config initialization.
