Subject: [PATCH 0661/1110] drm/amd/dal: Refactor DCE11 timing generator

Refactor timing generator for DCE11 to be called directly from DC rather than
exclusively through HWSS.

This is meant as a template to avoid always going through HWSS for all calls to HW.
This creates a better defined role for HWSS to only implement actual
sequences rather than as a generic layer.
