This reverts commit 55ad81f3510ec1a1c19e6a4d8a6319812d07d256.
optc dsc config was causing warnings due to missing register definitions. With the registers restored, the function can be re-enabled
The reverted commit also disabled sanity checks and dsc power gating. The sanity check warnings are not associated with dsc, and power gating on dsc still has an issue on non-dsc monitors where the dsc hardware block is never init and so cannot respond to power gating requests. Therefore, those are left as is
