drm/amd/display: Load DMCU IRAM
DMCU IRAM must be loaded by the driver before DMCU can function. Move the IRAM code out of the shadows and into a new file modules/power/power_helpers.c The IRAM table contains the backlight curve and ABM parameters Add this new file to the Makefiles Call dmcu_load_iram in late init of DM Move struct dmcu_version from dc.h to dmcu.h to allow dmcu to be included on its own Signed-off-by: David Francis <David.Francis@amd.com> Reviewed-by: Harry Wentland <harry.wentland@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
