drm/amd/display: wake up ogam mem pwr before programming ocsc

[Description]
OGAM_MEM_PWR could stay in light up when driver woke up to update gamma.
either disable MEM_LOW power feature or set to OGAM_bypass could make artificial color distortion goes away.
Easy reproduce after LOW_MEM Power feature enables and resume from S3.
