The V4L2_EVENT_EOS event is a deprecated behavior,
the V4L2_BUF_FLAG_LAST buffer flag should be used instead.

Save some power by disabling/enabling the jpeg clocks with
every stream stop/start.
Do not use DL_FLAG_RPM_ACTIVE in mxc_jpeg_attach_pm_domains,
to ensure power domains are off after probe.

It is only read-from, so make it const. In order to be able to do this,
constify all places where mxc_jpeg_fmt is used, in function arguments,
return values and pointers. On top of that, make the name a pointer to
const char.
On aarch64, this shrinks object code size with 550 bytes with gcc 11.1.0,
and almost 2kB with clang 12.0.0.

V4L2 driver for the JPEG encoder/decoder from i.MX8QXP/i.MX8QM application
processors.
The multi-planar buffers API is used.
Baseline and extended sequential jpeg decoding is supported.
Progressive jpeg decoding is not supported by the IP.
Supports encode and decode of various formats:
YUV444, YUV422, YUV420, RGB, ARGB, Gray
YUV420 is the only multi-planar format supported.
Minimum resolution is 64 x 64, maximum 8192 x 8192.
The alignment requirements for the resolution depend on the format,
multiple of 16 resolutions should work for all formats.
v4l2-compliance tests are passing, including the
streaming tests, "v4l2-compliance -s"
