V4L/DVB (13000): add driver for 774 Friio White USB ISDB-T receiver

This patch adds driver for 774 Friio White, ISDB-T USB receiver

Friio White is an USB 2.0 ISDB-T receiver. (http://www.friio.com/)
The device has a GL861 chip and a Comtech JDVBT90502 canned tuner module.
This driver ignores all the frontend_parameters except frequency,
as ISDB-T shares the same parameter configuration across the country
and thus the device can work like an intelligent one.

As this device does not include a CAM nor hardware descrambling feature,
the driver passes through scrambled TS streams.

There is Friio Black, a variant for ISDB-S, which shares the same USB
Vendor/Product ID with White, but it is not supported in this driver.
They should be identified in the initialization sequence,
but this feature is not tested.
