drm/amd/display: Remove stutter only configurations

drm/amd/display: Remove stutter only configurations

[ Upstream commit 71c4ca2d3b079d0ba4d9b3033641fea906cebfb6 ]

[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).
