media: rcar-vin: use scratch buffer and always run in continuous mode

Instead of switching capture mode depending on how many buffers are
available use a scratch buffer and always run in continuous mode. By
using a scratch buffer the responsiveness of the capture loop is
increased as it can keep running even if there are no buffers available
from userspace.

As soon as a userspace queues a buffer it is inserted into the capture
loop and returned as soon as it is filled. This is a improvement on the
previous logic where the whole capture loop was stopped and switched to
single capture mode if userspace did not feed the VIN driver buffers at
the same time it consumed them. To make matters worse it was difficult
for the driver to reenter continuous mode if it entered single mode even
if userspace started to queue buffers faster. This resulted in
suboptimal performance where if userspace where delayed for a short
period the ongoing capture would be slowed down and run in single mode
until the capturing process where restarted.

An additional effect of this change is that the capture logic can be
made much simple as we know that continuous mode will always be used.

refactoring where the scratch buffer can be used to avoid the need to

changed to use compound-literals and designated initializers to make

The compound-literals can also be used in assignment, which means we can
get rid of some temporary variables whose only purpose is to be
initialized by one of these anonymous structs and then serve as the
rvalue in an assignment expression.

A lot of the members of the default struct values used by the CSS API
were explicitly initialized to zero values.  Designated initializers
have allowed these members, and in some case whole default struct
values, to be removed.

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: radio: Critical interrupt bugfix for si470x over i2c

Fixed si470x_start() disabling the interrupt signal, causing tune
operations to never complete. This does not affect USB radios
because they poll the registers instead of using the IRQ line.
