[PATCH] pinctrl: equilibrium: add CONFIG_OF dependency

[Arnd Bergmann <arnd@xxxxxxxx>]

Without this, randconfig builds get a link failure

drivers/pinctrl/pinctrl-equilibrium.o: In function `pinconf_generic_dt_node_to_map_all':
pinctrl-equilibrium.c:(.text+0x96d): undefined reference to `pinconf_generic_dt_node_to_map'

Fixes: 1948d5c51dba ("pinctrl: Add pinmux & GPIO controller driver for a new SoC")
