[media] it913x [VER 1.07] Support for single ITE 9135 devices

Browse Source 
Support for single ITE 9135 device.

Only single devices have been tested.  Dual ITE 9135 devices
should work, but have not been tested.

TODOs
support for ver 2 chip
config for other tuner types.
rework of firmware file.
