pinctrl: rza1: Demote some kerneldoc headers and fix others

Some description blocks are void of any description/documentation,
others are missing 'struct' identifiers, there are also a couple of
misspellings of function parameter names.  Fix all of them.

Fixes the following W=1 kernel build warning(s):
