drm/amd/display: Update to correct min FCLK when construction BB

[Description] - For min FCLK, choose the min of 300Mhz and PMFW requirement - Also only apply min DET check in DML for non-UR cases Reviewed-by: Jun Lei <Jun.Lei@amd.com> Acked-by: Qingqing Zhuo <qingqing.zhuo@amd.com> Signed-off-by: Alvin Lee <Alvin.Lee2@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
