dvb: add driver for 774 Friio White USB ISDB-T receiver

From: Akihiro Tsukada <[email protected]>

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.

Priority: normal

---
Currently, all the Japanese Digital TV broadcasters, including the charge-free ones, scramble their programs except the tiny sized versions for cellular phones (called "1 seg." program).
"BCAS" card is used to descramble those normal sized programs, and a private agency named "BS Conditional Systems" exclusively issues the cards only as a bundle for the approved receiver devices. Friio White is not, so it does not include a BCAS card.

There are some descrambler software using a BCAS card from somewhere else with a PC/SC reader. Examples of these software include,
filter command: http://www.marumo.ne.jp/junk/arib_std_b25-0.2.4.lzh
Gstreamer plugin: http://2sen.dip.jp/cgi-bin/dtvup/source/up0158.zip
But you have to note that their use may violate the card's license agreement.

Committed, thanks. It would be good if you could add support for ISDB-T API [1] at the driver.
