drm/vc4: hdmi: Take our lock to reset the link
We access some fields protected by our internal mutex in
vc4_hdmi_reset_link() (saved_adjusted_mode, output_bpc, output_format)
and are calling functions that need to have that lock taken
(vc4_hdmi_supports_scrambling()).
However, the current code doesn't lock that mutex. Let's make sure it
does.
