drm/amd/display: Rewrite dccg42_init

Browse source

[why]

DCN42 reuses dccg42_init, which causes problems due to undefined masks.

[how]

- Read res_pool to determine the quantities of the respective resources
- Remove the physymclk root_clock_optimization check, as it seems like
  it shouldn't do anything (defaults to disabled already).
