pinctrl: npcm8xx: Fix incorrect struct npcm8xx_pincfg assignment

[ Upstream commit 113ec87b0f26a17b02c58aa2714a9b8f1020eed9 ]

Sparse is not happy about implementation of the NPCM8XX_PINCFG()

 pinctrl-npcm8xx.c:1314:9: warning: obsolete array initializer, use C99 syntax

which uses index-based assignment in a wrong way, i.e. it missed
the equal sign and hence the index is simply ignored, while the
entries are indexed naturally. This is not a problem as the pin
numbering repeats the natural order, but it might be in case of
shuffling the entries. Fix this by adding missed equal sign and
reformat a bit for better readability.
