drm/meson: Add support for HDMI encoder and DW-HDMI bridge + PHY 



The Amlogic Meson GXBB/GXL/GXM SoCs embeds a Synopsys DesignWare HDMI TX
Controller with a custom Bridge + PHY around the Controller.

This driver makes uses of all the custom PHY plat data callbacks and enables
the compatible HDMI modes to be configured as a drm_encoder instance.
