Adds the module option 'enable_msi' (type bool) which by default is

In comments and in the documentation, the units of properties marked
with the FE_SCALE_DECIBEL scale are specified in terms of 1/1000 dB
or 0.0001 dB. This is inconsistent, however, as 1/1000 is 0.001,
not 0.0001.
Note that the v4l-utils divide the value by 1000 for the signal
strength suggesting that the 1/1000 is correct.
Settle on millidecibels, ie. 1/1000dB or 0.001dB.

Add support in rc-core for drivers which implement the wakeup scancode
filter by encoding the scancode using the raw IR encoders. This is by
way of rc_dev::encode_wakeup which should be set to true to make the
allowed wakeup protocols the same as the set of raw IR encoders.
As well as updating the sysfs interface to know which wakeup protocols
are allowed for encode_wakeup drivers, also ensure that the IR
decoders/encoders are loaded when an encode_wakeup driver is registered.

Add the capability to encode RC-6 and RC-6A scancodes as raw events.
The protocol is chosen based on the specified protocol mask, and
whether all the required bits are set in the scancode mask, and none of
the unused bits are set in the scancode data.
The Manchester modulation helper is used several times with various
timings so that RC-6 header preamble, the header, header trailing bit
and the data itself can be modulated correctly.

Add the capability to encode RC-5, RC-5X and RC-5-SZ scancodes as raw
events. The protocol is chosen based on the specified protocol mask,
and whether all the required bits are set in the scancode mask, and
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
the generic Manchester encoder available in rc-core.

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.

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.

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.
