pinctrl: actions: remove MODULE_LICENSE in non-modules

Since commit 8b41fc4454e ("kbuild: create modules.builtin without
Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations
are used to identify modules. As a consequence, uses of the macro
in non-modules will cause modprobe to misidentify their containing
object file as a module when it is not (false positives), and modprobe
might succeed rather than failing with a suitable error message.

So remove it in the files in this commit, none of which can be built as
modules.

pinctrl: actions: pinctrl-s700: Constify s700_padinfo[]

The only usage of s700_padinfo[] is to assign it to the padinfo field in
the owl_pinctrl_soc_data struct, which is a const pointer. Make it const
to allow the compiler to put it in read-only memory.

documentation defined names.

This fixes following errors when groups names defined on documentation are used:
