The use of a macro named 'RST' conflicts with one of the same name
in arch/mips/include/asm/mach-rc32434/rb.h. This causes build
warnings on some MIPS builds.
Change the names of the JPEG marker constants to be in their own
namespace to fix these build warnings and to prevent other similar
problems in the future.
Fixes these build warnings:

The runtime enabling of the ISPCK (internally clocks the pipeline inside
the ISC) has to be done after the pm_runtime for the ISC dev has been
started.
After the commit by Mauro:
the ISC failed to probe with the error:
atmel-sama5d2-isc f0008000.isc: failed to enable ispck: -13
atmel-sama5d2-isc: probe of f0008000.isc failed with error -13
This is because the enabling of the ispck is done too early in the probe,
and the PM runtime returns invalid request.
Thus, moved this clock enabling after pm_runtime_idle is called.
The ISPCK is required only for sama5d2 type of ISC.
Thus, add a bool inside the isc struct that is platform dependent.
For the sama7g5-isc, the enabling of the ISPCK is wrong and does not make
sense. Removed it from the sama7g5 probe. In sama7g5-isc, there is only
one clock, the MCK, which also clocks the internal pipeline of the ISC.
Adapted the clk_prepare and clk_unprepare to request the runtime PM
for both clocks (MCK and ISPCK) in case of sama5d2-isc, and the single
clock (MCK) in case of sama7g5-isc.

When adding an internal scratch buffer to improve buffer handling when
stopping it was also erroneously used when syncing at capture start.
This led to that the first three buffers captured were always dropped
as they were captured in the scratch buffer instead of in a buffer
provided by the user.
Allow the hardware to be given user provided buffers when preparing for
capture in the stopped state. This still allows the driver to sync with
the hardware and always completes the buffers to user-space in the
correct order as no buffers are completed before the sync is complete.
This change improves the driver as buffers are completed and given to
the user three frames earlier than before.
The change also fixes a warning produced by v4l2-compliance,
