The are only HIST_ENTRIES worth of entries in hist_entry however the
for-loop is iterating one too many times leasing to a read access off
the end off the array ctrls->hist_entry. Fix this by iterating by
the correct number of times.

Image Sensor Controller has an internal image processor.
It can convert raw format to the other formats, like
RGB565, YUV420P. A module parameter 'sensor_preferred'
is used to enable or disable the pipeline function.
Some v4l2 controls are added to tuning the image when
the pipeline function is enabled.

The newly added atmel-isc driver uses SET_RUNTIME_PM_OPS() to
refer to its suspend/resume functions, causing a warning when
CONFIG_PM is not set:
media/platform/atmel/atmel-isc.c:1477:12: error: 'isc_runtime_resume' defined but not used [-Werror=unused-function]
media/platform/atmel/atmel-isc.c:1467:12: error: 'isc_runtime_suspend' defined but not used [-Werror=unused-function]
This adds __maybe_unused annotations to avoid the warning without
adding an error-prone #ifdef around it.

Add driver for the Image Sensor Controller. It manages
incoming data from a parallel based CMOS/CCD sensor.
It has an internal image processor, also integrates a
triple channel direct memory access controller master
interface.
