pinctrl: sh-pfc: r8a7796: Fix NFDATA{0..13} and NF{ALE,CLE,WE_N,RE_N} pin function definitions

This patch fixes the implementation incorrect of IPSR register value
definitions for NFDATA{0..13} and NF{ALE,CLE,WE_N,RE_N} pins function.

This is a correction to the incorrect implementation of IPSR register
