Use syscon_regmap_lookup_by_phandle_args() which is a wrapper over
syscon_regmap_lookup_by_phandle() combined with getting the syscon
argument. Except simpler code this annotates within one line that given
phandle has arguments, so grepping for code would be easier.
Th
mtk_hdmi.h header
so, while at it, also remove it.

Change error prints to use dev_err_probe() instead of dev_err()
where possible in function mtk_hdmi_dt_parse_pdata(), used only
