media: platform: synopsys: Add support for HDMI input driver 



Add initial support for the Synopsys DesignWare HDMI RX
Controller Driver used by Rockchip RK3588. The driver
supports:
 - HDMI 1.4b and 2.0 modes (HDMI 4k@60Hz)
 - RGB888, YUV422, YUV444 and YCC420 pixel formats
 - CEC
 - EDID configuration

The hardware also has Audio and HDCP capabilities, but these are
not yet supported by the driver.

	  Support for Synopsys HDMI HDMI RX Controller.

	  This driver supports HDMI 2.0 version.



	  To compile this driver as a module, choose M here. The module

	  will be called synopsys_hdmirx.

	help

	  Preload default EDID (Extended Display Identification Data)

	  branded by Linux Foundation that exposes display modes up

	  to 4k@30Hz, which have best compatibility with HDMI transmitters.



	  Enabling this option is recommended for a non-production use-cases.

	  It will make driver usable out-of-the-box.



	  For a higher display modes you will need to load customized EDID

	  from userspace using v4l2-ctl tool or by other means.



	  Without enabling this option driver will be practically

	  non-functional until EDID will be loaded from userspace.

	  Which is a wanted behavior when using this driver in a

	  commercial product that should utilize own branded EDID.
