[PATCH v14 2/7] phy: Add HDMI configuration options

[Sandor Yu <Sandor.yu@xxxxxxx>]

Allow HDMI PHYs to be configured through the generic
functions through a custom structure added to the generic union.

The parameters added here are based on HDMI PHY
implementation practices.  The current set of parameters
should cover the potential users.
