media: atomisp: Drop ia_css_debug_dump_debug_info() and functions only used by it

ia_css_debug_dump_debug_info() is defined but never called anywhere,
drop it.

Also drop all the other ia_css_debug_dump_* functions only called by
ia_css_debug_dump_debug_info(), as well as *_get_state() functions only
used by those.
