[PATCH v5 06/10] phy: rockchip: samsung-hdptx: Drop TMDS rate setup workaround

[Cristian Ciocaltea]

Since commit ba9c2fe18c17 ("drm/rockchip: dw_hdmi_qp: Switch to
phy_configure()") the TMDS rate setup doesn't rely anymore on the
unconventional usage of the bus width, instead it is managed exclusively
through the HDMI PHY configuration API.

Drop the now obsolete workaround to retrieve the TMDS character rate via
phy_get_bus_width() during power_on().
