phy: rockchip: samsung-hdptx: Setup TMDS char rate via phy_configure_opts_hdmi

Browse source

The current workaround to setup the TMDS character rate relies on the
unconventional usage of phy_set_bus_width().

Make use of the recently introduced HDMI PHY configuration API to
properly handle the setup.  The workaround will be dropped as soon as
the switch has been completed on both ends.

Rename rk_hdptx_phy_verify_config() to rk_hdptx_phy_verify_dp_config()
and introduce the rk_hdptx_phy_verify_hdmi_config() helper to check the
HDMI parameters during phy_configure().
