Subject: [PATCH 0/4] Add DSC v1.2 Support for DSI

This is a series of changes for DSI to enable support for DSC v1.2.

This includes:

1) Dividing the pclk_rate by the compression ratio when DSC is enabled
2) Fixing the word count calculation for DSC
3) Setting the DATA_COMPRESS bit when DSC is enabled

With these changes (and the dependency below), DSC v1.2 should work over
DSI.

Depends-on: "add DSC 1.2 dpu supports" [1]
