The pfc parameter of the .pin_to_pocctrl() method was never used.
It is a relic of the old I/O voltage handling before commit
8775306d ("pinctrl: sh-pfc: refactor voltage setting").

Remove the parameter, as it prevents the checker from calling this
function for validating consistency of the pin control tables.
