The MIPI_CSIS_ISPCFG_ALIGN_32BIT bit enables output of 32-bit data. The
driver sets it based on the select format, but no format uses a 32-bit
bus width, so the bit is never set in practice. This isn't likely to
change any time soon, as the CSI IP core connected at the output of the
CSIS doesn't support 32-bit data width. Hardcode the bit to 0.

The total number of bits per line needs to be a multiple of 8, which
requires aligning the image width based on the format width. The
csis_pix_format structure contains a pix_width_alignment field that
serves this purpose, but the field is never set. Instead of fixing that,
calculate the alignment constraints based on the bus width for the
format, and drop the unneeded pix_width_alignment field.

Pad formats for the active configuration are manually initialized in
mipi_csis_subdev_init(), while pad formats for the TRY configurations
are initialized by the subdev .init_cfg() operation. This creates a risk
of the two configurations not being synchronized. Fix it by initializing
formats in the .init_cfg() operation only, and calling it from
mipi_csis_subdev_init().

The subdev set pad format operation currently misbehaves in multiple ways:
- mipi_csis_try_format() unconditionally stores the format in the device
state, even for V4L2_SUBDEV_FORMAT_TRY.
- The format is never stored in the pad cfg, but the pad cfg format
always overwrites the format requested by the user.
- The sink format is not propagated to the source.
Fix all this by reworking the set format operation as follows:
1. For the source pad, turn set() into get() as the source format is not
modifiable.
2. Validate the requested format and updated the stored format
accordingly.
3. Return the format actually set.
4. Propagate the format from sink to source.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

This spinlock is used solely to call v4l2_m2m_buf_done().
Since buffers are obtained only after being removed
from the ready queue, there's no concurrent access, and
so no need for synchronization.
Remove the spinlock to make sure no one copies this pattern.
Some archaeology shows this is a small leftover from ancient code.
This driver (then called m2m_testdev) used the videobuf1 framework;
commit d80ee38cd8 ("[media] v4l: mem2mem: port m2m_testdev to vb2")
converted it to videobuf2. The spinlock was then no longer needed,
and this simply went unnoticed.

Similar to commit 9ee50a9489 ("media: coda: lock capture queue wakeup
against encoder stop command"), make sure that a JPEG decoder stop
command running concurrently with a decoder finish_run always either
flags the last returned buffer or wakes up the capture queue to signal
the end of stream condition afterwards.
This was not necessary for BIT processor contexts because of the need to
release the bitstream buffer with the stream end condition. In contrast,
the JPEG decoder can be finished with decoding the image between the
time the application queues the last output buffer and the time it
issues the decoder stop command.

Add helpers for JPEG header parsing. They allow both scanning for marker
segment positions and later parsing the segments individually, as
required by s5p-jpeg, as well as parsing all headers in one go, as
required by coda-vpu. The frame header is always parsed, as basically
all decoders are interested in width, height, and number of components.
For convenience, the JPEG chroma subsampling factors are decoded into a
v4l2_jpeg_chroma_subsampling enum.
Only baseline and extended sequential DCT encoded JPEGs with 8-bit or
