[media] cx24120: i2c-max-write-size is now configurable

Some i2c-hosts are quite limited regarding maximum

[media] Add support for TechniSat Skystar S2

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.

none of the unused bits are set in the scancode data. For example a
scancode filter with bit 16 set in both data and mask is unambiguously
RC-5X.

The Manchester modulation helper is used, and for RC-5X it is used twice
with two sets of timings, the first with a short trailer space for the
space in the middle, and the second with no leader so that it can
continue the space.

The encoding in RC-5-SZ first inserts a pulse and then simply utilizes

[media] saa7134-i2c: make debug macros to use pr_fmt()

Converting debug prints to use pr_foo() is not trivial, as the
result will be a way worse than what's provided here, due to the
pieces of the code that prints the I2C transfers. Those use a
lot pr_cont(), and, depending on using either level 1 or 2,
a different set of macros are selected.

So, let's replace d1printk() and d2printk() macros by i2c_dbg()
and i2c_count() adding a debug level there.

[media] saa7134: better handle core debug messages

On media drivers, debugging messages should be grouped into
categories, as this makes easier to debug the driver.

In the case of saa7134, the core has 2 debug categories, one
for IRQ, and another one for the core itself. The IRQ have
actually 2 levels of debug.

So, instead of using pr_dbg(), where everything would be in
the same box, let's define two macros that use pr_fmt(),
one for the core, and another one for irq.

With that, we can replace the remaining printk() occurrences
at the core to use either core_dbg() or irq_dbg(), depending
on the group of debug macros that need to be enabled.

[media] rtl2832: add support for GoTView MasterHD 3 USB tuner

GoTView MasterHD 3 is a DVB-T2/C USB 2.0 tuner.

It's based on the following components:
- USB bridge: RTL2832P (contains also DVB-T demodulator)
- Demodulator: Si2168-A30
- Tuner: Si2148-A20

The demodulator and the tuner will need firmwares. The Si2148 uses Si2158
firmware. Antti has the firmwares available for download:
http://palosaari.fi/linux/v4l-dvb/firmware/

Do note that for DVB-T either of the demodulators can be used. DVB-C and
DVB-T2 are only supported by the Si2168 demodulator. The driver will
register 2 frontends for the same adapter. Frontend 0 will be the RTL2832
demodulator and frontend 1 will be the Si2168 demodulator. The same
tuner is used for both.

As a consequence of the above, it's recommended to use application that
does implement proper DVBv5 support.

For some reason, the old I2C write method sporadically fails. Thus the
need for an option to only use the new I2C write method supported by the
RTL2832.

Rather than making a new BGR444 format (as I proposed initially), Jon prefers
to just fix this and return the colors in the right order. I think that makes
sense in this case.

Since the RGB444 pixel format is deprecated due to the ambiguous specification
of the alpha component we use the XRGB444 pixel format instead (specified as having
no alpha channel).
