drm/amd/display: Remove stutter only configurations

2023-02-14T21:04:28+00:00

[why] Newer ASICs such as DCN314 needs to allow for both self refresh and mem clk switching rather than just self refresh only. Otherwise, we can see some p-state hangs on ASICs that do support mem clk switching. [how] Added an allow_self_refresh_only flag for dcn30_internal_validate_bw and created a validate_bw method for DCN314 with the allow_self_refresh_only flag set to false (to support mem clk switching).
