[PATCH v2] pinctrl: single: fix function name in documentation

[Drew Fustini]

Use the correct the function name in the documentation for
"pcs_parse_one_pinctrl_entry()".

"smux_parse_one_pinctrl_entry()" appears to be an artifact from the
development of a prior patch series ("simple pinmux driver") which
transformed into pinctrl-single.
