[PATCH v2 1/9] media: synopsys: hdmirx: add media device infrastructure

[Sascha Hauer]

From: Gerald Loacker <gerald.loacker@xxxxxxxxxxxxxx>

Initialize the media device to enable integration with HDMI bridge
devices in the video capture pipeline. This provides the foundation
for representing the hardware topology through the media controller
framework.
