phy: rockchip: inno-hdmi: Remove deprecated way to configure TMDS rate

Browse Source 
The TMDS character rate of this PHY is configured using PHY bus width
in downstream vendor kernel and out-of-tree patches, however no in-tree
consumer of this PHY has ever called phy_set_bus_width() to change the
TMDS character rate as currently only 8-bit RGB output is supported by
the HDMI display driver.

The series "Split Generic PHY consumer and provider" clarifies that
phy_set_bus_width() is intended as a provider-only function.

Remove the deprecated unused fallback way to configure TMDS character
rate now that this HDMI PHY support using phy_configure() to configure
the TMDS character rate.
