drm/sun4i: Set TCON clock inside sun4i_tconX_mode_set
Currently we are configuring the TCON's dot clock or special clock
directly from the encoder mode_set functions. Since we already
provide mode_set helper functions for the TCON's 2 channels, we
can set the respective clock from those helpers, and reduce the
exposure of the TCON's internals.
