[PATCH v2] drm/amd/display: Enable HDMI FRL by default

[Fangzhi Zuo <jerry.zuo@amd.com>]

FRL (Fixed Rate Link) is required to drive HDMI 2.1 high-bandwidth
modes and is broadly supported on capable sinks, but it was left
disabled unless a user explicitly opted in via the
amdgpu.dcfeaturemask module parameter.

Enable it by default by adding DC_FRL_MASK to the default
amdgpu_dc_feature_mask value, keeping the mask semantics unchanged.
