drm/sun4i: tcon-top: Fix return type warning

When commit af11942ee4 ("drm/sun4i: tcon-top: Cleanup clock handling")
was merged, the error handling path of the of_property_match_string was
changed to take into account the fact that the returned value of that
function wasn't an error pointer but an error code.

Unfortunately, this introduced a warning since the now returned value is an
integer, while the sun8i_tcon_top_register_gate function should return an
error pointer.

Fix that by calling ERR_PTR.
