Since the debug codes around #ifdef HAS_WATCHDOG_SP_THREAD_DEBUG are
no longer used, the debug implementation of this can be removed.

Since some parts of the data structure elements are determined in compile
time, the configuration data structure should be compiled for both two
ISP models. In order to set the configuration for both ISP models in
runtime, The sh_css_sp_group is unified to one data structure for the
configuration to ensure the data structure can be used for both ISP2400
and 2401 in runtime. Also, the unused codes for debug purpose are removed.
Form the aspect of ISP setting, the length and the content of the
configuration structure for ISP2400 and ISP2401 are different. So, we
need to pick up the necessary part of sp_group configuration for both
models and then copy those parts into a temporary buffer. This buffer
is finally written to the ISP with the corresponding length.

Hi Kate,
Thank you for the new version. One small remark below.

And ending here.
Really belongs in: [PATCH v3 2/3] media: atomisp: Removed unused
HAS_WATCHDOG_SP_THREAD_DEBUG debug.
I have moved this patch hunk to patch 2/3 while merging this
series into my atomisp branch:
https://git.kernel.org/pub/scm/linux/kernel/git/hansg/linux.git/log/?h=media-atomisp
