Use regmap for I2C register access.
Remove own I2C repeated mutex as it should not be needed. I2C adapter
lock is already taken when I2C mux adapter is called, no need for
double locking.

This patch adds support for the Technisat Skystar S2 - this
has been tried before but the cx24120 driver was a bit out of shape
and it didn't got any further:
https://patchwork.linuxtv.org/patch/10575/
It is an old card, but currently being sold off for next to nothing,
so it's proving quite popular of late. Noticing it's quite similar
to the cx24116 and cx24117 I've rewritten the driver in a similar way.
There were a few registers and commands from those drivers
missing from this one I've tested out and found they do something so
they've been added in to speed up tuning and to make get_frontend
return something useful.

Convert driver to I2C RegMap API. That offers unified register

We need 3 register maps, one for each register page, as chips has

This patch adds driver for tc90522 demodulator chips.
The chip contains 4 demod modules that run in parallel and are independently
controllable via separate I2C addresses.
Two of the modules are for ISDB-T and the rest for ISDB-S.
It is used in earthsoft pt3 cards.
Note that this driver does not init the chip,
because the initilization sequence / register setting is not disclosed.
Thus, the driver assumes that the chips are initilized externally
by its parent board driver before fe->ops->init() are called.
Earthsoft PT3 PCIe card, for example, contains the init sequence
in its private memory and provides a command to trigger the sequence.

Driver for the CIMaX SP2 common interface chip. It is very much based on
the existing cimax2 driver for cx23885, but should be more reusable. The
product has been sold with name Atmel T90FJR as well and the data sheets
for that chip seem to be publicly available.
It seems that the USB device that I have and the cx23885 based devices will
need to interact differently with the chip for the CAM operations. Thus
there is one callback function that is passed on to the sp2 driver
(see function sp2_ci_op_cam for that one).
IRQ functionality is not included currently (not needed by USB devices
and I don't have a PCIe device for development).

Switch standard I2C adapter to muxed I2C adapter.

I discussed with Jean and he suggested to implement it as a
multiplexed i2c adapter because tuner I2C bus could be seen like

DVB_FE_CUSTOMISE is set. But that Kconfig symbol was replaced with
MEDIA_SUBDRV_AUTOSELECT as of v3.7. So use the new symbol. And negate

Instead of having 3 options to allow customizing the media
sub-drivers (tuners, I2C drivers, frontends), merge all of
them into just one.
That simplifies the life for users, as they can just keep
this untouched.
Life for developers is also simpler, as there's now just
one Kconfig item to remember, for the ancillary sub-drivers
providing supports for chips that could change from one
board design to another.
