[media] ngene: CXD2099AR Common Interface driver

Driver for the Common Interface Controller CXD2099AR.
Supports the CI of the cineS2 DVB-S2.

For now, data is passed through '/dev/dvb/adapterX/sec0':
- Encrypted data must be written to 'sec0'.
- Decrypted data can be read from 'sec0'.
- Setup the CAM using device 'ca0'.
