[media] media: platform: add VPFE capture driver support for AM437X
This patch adds Video Processing Front End (VPFE) driver for
AM437X family of devices
Driver supports the following:
- V4L2 API using MMAP buffer access based on videobuf2 api
- Asynchronous sensor/decoder sub device registration
- DT support
