dvb-usb/friio, dvb-usb-v2/gl861: decompose friio and merge with gl861

From: Akihiro Tsukada <[email protected]>

Friio device contains "gl861" bridge and "tc90522" demod, for which the separate drivers are already in the kernel. But friio driver was monolithic and did not use them, practically copying those features.
This patch decomposes friio driver into sub drivers and re-uses existing ones, thus reduces some code.

It adds some features to gl861,
to support the friio-specific init/config of the devices and implement i2c communications to the tuner via demod with USB vendor requests.

---
Changes since v6:
- separate algorithm/adapter for tuner i2c
- remove the hack for module ref-counting (fix in the tuner driver)
- cut redundant sleeps in friio init/config
- add comments on Friio-specific init/config and i2c

Changes since v5:
- specify chip name literally

Changes since v4:
- use new style of specifying pll_desc id of the tuner driver

Changes since v3:
- make dvb_usb_device_properties static

Changes since v2:
(patch #27928, dvb-usb-friio: split and merge into dvb-usbv2-gl861)
- used the new i2c binding helpers instead of my own one
- merged gl861-friio.c with gl861.c
