[media] af9035: Add support for IT930x USB bridge
Add support for IT930x USB bridge and IT9303 reference design. It is a DVB-T/T2/C tuner with the following components: - IT9303 USB bridge - Si2168-B40 demodulator - Si2147-A30 tuner The IT9303 requires firmware that can be downloaded here: http://trsqr.net/olli/linux/firmwares/it930x/ The Si2168-B40 requires firmware, but the one that is used by PCTV 292e can be used. http://palosaari.fi/linux/v4l-dvb/firmware/Si2168/Si2168-B40/ The Si2147-A30 tuner does not require firmware loading.
