From: Akihiro Tsukada <tskd08@gmail.com>
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 v4:
- use new style of specifying pll_desc 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
