[PATCH -next] pinctrl: nuvoton: wpcm450: Fix build error without OF

[Zheng Bin <zhengbin13@xxxxxxxxxx>]

If OF is not set, bulding fails:

drivers/pinctrl/nuvoton/pinctrl-wpcm450.o: In function `wpcm450_dt_node_to_map':
pinctrl-wpcm450.c:(.text+0x404): undefined reference to `pinconf_generic_dt_node_to_map'

Make PINCTRL_WPCM450 depends on OF to fix this.
