The strncpy() function is being deprecated upstream. Replace
it by the safer strscpy().
While here, replace a few occurences of strlcpy() that were
recently added to also use strscpy().

The CSI controller can take raw data from the data bus and output it
directly to capture buffers. This can be used to support the JPEG media
bus format.
While the controller can report minimum and maximum bytes per line, it
has no way to report how many lines were captured in the last frame.
Thus, even when the on-bus data is framed correctly, we have no way to
accertain the actual amount of data captured, unless we scan the buffer
for JPEG EOI markers, or sequential zeros. For now we leave bytesused
alone, and leave it up to userspace applications to parse the data.

The CSI controller can take raw data from the data bus and output RGB565
format. The controller does not distinguish between RGB565 LE and BE.
Instead this is determined by the media bus format, i.e. the format or
order the sensor is sending data in.

There are a few other coding style issues reported by checkpatch
while in --strict mode. Fix the ones that make sense.

Make checkpatch.pl happier by running it on strict mode and
using the --fix-inline to solve some issues.
