pinctrl: sh-pfc: sh73a0: Fix fsic_spdif pin groups

BugLink: https://bugs.launchpad.net/bugs/1864773

[ Upstream commit 0e6e448b ]

There are two pin groups for the FSIC SPDIF signal, but the FSIC pin
group array lists only one, and it refers to a nonexistent group.

Fixes: 2ecd4154 ("sh-pfc: sh73a0: Add FSI pin groups and functions")
