[PATCH -next] pinctrl: fix build, PINCTRL_CYGNUS_MUX depends on OF

[Randy Dunlap]

From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

Fix pinctrl-cygnus-mux.c build when ARCH_BCM_CYGNUS is not enabled
but COMPILE_TEST is enabled by making the driver depend on OF.

../drivers/pinctrl/bcm/pinctrl-cygnus-mux.c:739:20: error: 'pinconf_generic_dt_node_to_map_group' undeclared here (not in a function)
  .dt_node_to_map = pinconf_generic_dt_node_to_map_group,
