Subject: [PATCH] pinctrl: renesas: rzn1: enable PINMUX

Enable pin muxing (eg. programmable function), so that the RZN1 GPIO
pins will be configured as specified by the pinmux in the DTS.

This used to be enabled implicitly via CONFIG_GENERIC_PINMUX_FUNCTIONS,
however that was removed in 308fb4e4eae14e6189dece3b7cf5b5f453c5d02
since the rzn1 driver does not call any of the generic pinmux functions.

You probably need to point at this commit with a Fixes and possibly Cc
this to stable. Also you should use proper formatting for the commit
(12 digits sha then the text inside ("...")).
