ipa: rkisp1: Drop use of utils::defopt

utils::defopt causes compilation issues on gcc 8.0.0 to gcc 8.3.0,
likely due to bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86521
that was fixed in gcc 8.4.0. gcc 8.3.0 may be considered old (libcamera
requires gcc-8 or newer), but it is shipped by Debian 10 that has LTS
support until mid-2024.

As no workaround has been found to fix compilation on gcc 8.3.0 while
still retaining the functionality of utils::defopt, stop using it in the
RkISP1 IPA module.
