media: add tuner standby op, use where needed
The v4l2_subdev core s_power op was used for two different things: power on/off
sensors or video decoders/encoders and to put a tuner in standby (and only the
tuner!). There is no 'tuner wakeup' op, that's done automatically when the tuner
is accessed.
The danger with calling (s_power, 0) to put a tuner into standby is that it is
usually broadcast for all subdevs. So a video receiver subdev that supports
s_power will also be powered off, and since there is no corresponding (s_power, 1)
they will never be powered on again.
In addition, this is specifically meant for tuners only since they draw the most
current.
This patch adds a new tuner op called 'standby' and replaces all calls to
(core, s_power, 0) by (tuner, standby). This prevents confusion between the two
uses of s_power. Note that there is no overlap: bridge drivers either just want
to put the tuner into standby, or they deal with powering on/off sensors. Never
both.
This also makes it easier to replace s_power for the remaining bridge drivers
with some PM code later.
Whether we want something cleaner for tuners in the future is a separate topic.
There is a lot of legacy code surrounding tuners, and I am very hesitant about
making changes there.

media: ngene: compensate for TS buffer offset shifts
A possible hardware bug was discovered when using CA addon hardware
attached to the ngene hardware, in that the TS input buffer much likely
will shift and thus become unaligned to 188 byte blocks (a full TS frame)
when things like CA module initialisation (which happens via differing
communication paths) take place. This causes the TS NULL removal in
tsin_exchange() to fail to detect this previously inserted data and thus
causes userspace applications to receive data they didn't sent beforehand
and ultimately cause troubles.
On driver load with an inserted CAM, buffers are fine at first (note that
the driver has to keep the communication running from/to the card by
inserting TS NULL frames, this is done in tsout_exchange() via
FillTSBuffer() - that data is simply sent back by the hardware):
offset | 0 1 2 3 4 5 .... 188 189 190 191 192 193 .... 376
data | 47 1f ff 10 6f 6f .... 47 1f ff 10 6f 6f .... 47
After a few seconds, the CA module is recognised and initialised, which is
signalled by
dvb_ca_en50221: dvb_ca adapter X: DVB CAM detected and initialised successfully
This is where the first shift happens (this is always four bytes), buffer
becomes like this:
offset | 0 1 2 3 4 5 .... 188 189 190 191 192 193 .... 376
data | 6f 6f 6f 6f 47 1f .... 6f 6f 6f 6f 47 1f .... 6f
Next, VDR, TVHeadend or any other CI aware application is started, buffers
will shift by even more bytes. It is believed this is due to the hardware
not handling control and data bytes properly distinct, and control data
having an influence on the actual data stream, which we cannot properly
detect at the driver level.
Workaround this hardware quirk by adding a detection for the TS sync byte
0x47 before each TS frame copy, scan for a new SYNC byte and a TS NULL
packet if buffers become unaligned, take note of that offset and apply
that when copying data to the DVB ring buffers. The last <188 bytes from
the hardware buffers are stored in a temp buffer (tsin_buffer), for which
the remainder will be in the beginning of the next hardware buffer (next
iteration of tsin_exchange()). That remainder will be appended to the
temp buffer and finally sent to the DVB ring buffer. The resulting TS
stream is perfectly fine, and the TS NULL packets inserted by the driver
which are sent back are properly removed. The resulting offset is being
clamped to 188 byte segments (one TS packet). Though this can result in
a repeated TS packet if the overall offset grows beyond this (and it
will grow only on CA initialisation), this is still way better than
unaligned TS frames and data sent to userspace that just isn't supposed
to be there.
This compensation can be toggled by the ci_tsfix modparam, which defaults
to 1 (enabled). In the case of problems, this can be turned off by setting
the parameter to 0 to restore the old behaviour.

media: ngene: move the tsin_exchange() stripcopy block into a function
Move the copy logic that will skip previously inserted TS NULL frames when
moving data to the DVB ring buffers into an own function. This is done to
not duplicate code all over the place with the following TS offset shift
fixup patch.
While we're touching this part of the code, get rid of the DEBUG_CI_XFER
debug-ifdeffery. This could be toggleable either by a Kconfig or a module
param, but in the end this will accidentally be enabled and cause lots
of kernel log messages, and such devel debug shouldn't be there anyway.
