pinctrl: pinctrl-single: Remove some unused fields in struct pcs_func…

…tion

In "struct pcs_function", the 'pgnames' and 'npgnames' fields are unused.
This is a left-over from commit 571aec4 ("pinctrl: single: Use generic
pinmux helpers for managing functions");

Remove them.

Found with cppcheck, unusedStructMember.
