media: mtk-vcodec: Add to support multi hardware decode

2022-01-23T20:18:45Z

There are more than two hardwares for decoder: LAT0, LAT1 and CORE. In order to manage these hardwares, register each hardware as independent platform device for the larbs are different. Each hardware module controls its own information which includes interrupt/power/clocks/registers. Calling of_platform_populate in parent device, and use subdev_bitmap to record whether the hardwares are registered.
