[PATCH v2 16/28] drm: omapdrm: hdmi: Store PLL hardware data in HDMI transmitter drivers

The HDMI PLL hardware data are dependent on the HDMI transmitter model.
The PLL driver contains hardware data for all supported transmitters,
and selects the appropriate hardware data based on the OMAP SoC version.
It makes more sense to store the PLL hardware data in the HDMI
transmitter drivers and pass them to the HDMI PLL initialization
function, as the HDMI transmitter drivers are transmitter-specific and
don't need to check the OMAP SoC version.
