[PATCH] pinctrl: th1520: add a CONFIG_OF dependency

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

When compile-testing without CONfIG_OF:

drivers/pinctrl/pinctrl-th1520.c: In function 'th1520_pinctrl_dt_node_to_map':
drivers/pinctrl/pinctrl-th1520.c:455:23: error: implicit declaration of function 'pinconf_generic_parse_dt_config'; did you mean 'pinconf_generic_dump_config'? [-Wimplicit-function-declaration]
  455 |                 ret = pinconf_generic_parse_dt_config(child, pctldev, &configs, &nconfigs);
      |                       ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      |                       pinconf_generic_dump_config

Enforce this using Kconig dependencies.
