drm/amd/display: Add AV mute wait frames to dce110_set_avmute

Browse source

Port the three-frame wait logic from dcn30_set_avmute to
dce110_set_avmute so that older DCN versions (1.0, 2.0) also
wait for GCP packets to be sent out before proceeding.

This ensures HDMI sinks properly process the mute state,
preventing garbled display after link re-establishment.
