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.

Before starting a capture, allocate a scratch buffer which can be used
by the driver to give to the hardware if no buffers are available from
userspace. The buffer is not used in this patch but prepares for future
refactoring where the scratch buffer can be used to avoid the need to
fallback on single capture mode if userspace can't queue buffers as fast
as the VIN driver consumes them.

When loading the budget_av driver for ie. a KNC1 DVB-C TDA10024 card,
which makes use of the ttpci eeprom check functionality (that always
fails on these cards, but that's no issue at all), this is printed
to the kernel log:

with the 'ff' being repeated for a total of 20 times. Improve that by
using the %*phC format specifier instead dprintk()'ing every byte of the

Basically, v4l2_find_nearest_size() callers pass 5 arguments,
while its definition require 6 args.

Unfortunately, my build process was also broken, as it was reporting me that
the compilation went fine:

	*** ERRORS ***

	*** WARNINGS ***

That was due to a change here to use of linux-log-diff script that
provides a diffstat between the errors output. Somehow, the logic
was missing some fatal errors.

The CSS API uses a lot of nested anonymous structs defined in object
macros to assign default values to its data-structures.  These have been
changed to use compound-literals and designated initializers to make
them more comprehensible and less fragile.

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.
