[media] media: ti-vpe: Add CAL v4l2 camera capture driver

The Camera Adaptation Layer (CAL) is a block which consists of a dual
port CSI2/MIPI camera capture engine.
Port #0 can handle CSI2 camera connected to up to 4 data lanes.
Port #1 can handle CSI2 camera connected to up to 2 data lanes.
The driver implements the required API/ioctls to be V4L2 compliant.
Driver supports the following:
    - V4L2 API using DMABUF/MMAP buffer access based on videobuf2 api
    - Asynchronous sensor sub device registration
    - DT support
