[PATCH] pinctrl: nuvoton: Fix sparse warning

[Linus Walleij]

Sparse complains:
drivers/pinctrl/nuvoton/pinctrl-wpcm450.c:626:9:
sparse: sparse: obsolete array initializer, use C99 syntax

This is because no equal sign is between the array index
and the assignments, in the macro.

Fix it up.

You will find the same in the pinctrl-npcm7xx driver:

 #define NPCM7XX_PINCFG(a, b, c, d, e, f, g, h, i, j, k) \
        [a] { .fn0 = fn_ ## b, .reg0 = NPCM7XX_GCR_ ## c, .bit0 = d, /*...*/  }
