[PATCH v10 11/14] media: iris: Add hooks for pixel and non-pixel context banks

From: Vikash Garodia <[email protected]>

Iris platforms use separate context-bank devices for the pixel, non-pixel
firmware domains. Add platform hooks to create and destroy those
subdevices, providing a interface for their lifecycle management across
platforms.
