drm/amd/display: Check for tg ops in dce110_set_avmute
Some older DCE timing generators do not implement is_tg_enabled in
their ops table. Calling it unconditionally when waiting for AV mute
frames causes a NULL pointer dereference on Southern Islands dGPUs
when turning the display off over HDMI.
Check that tg and the required ops exist before waiting for frames.
Fixes: 414da24137ac ("drm/amd/display: Add AV mute wait frames to dce110_set_avmute")
Closes: https://gitlab.freedesktop.org/drm/amd/-/work_items/5557
