drm: bridge: dw-hdmi: Create PHY operations
The HDMI TX controller support different PHYs whose programming interface can vary significantly, especially with vendor PHYs that are not provided by Synopsys. To support them, create a PHY operation structure that can be provided by the platform glue layer. The existing PHY handling code (limited to Synopsys PHY support) is refactored into a set of default PHY operations that are used automatically when the platform glue doesn't provide its own operations.
