pinctrl: sh-pfc: r8a7791: Fix SCIF2 pinmux data

commit 58439280 upstream.

PINMUX_IPSR_MSEL() macro invocation for the TX2 signal has apparently wrong
1st argument -- most probably a result of cut&paste programming...

 - Use PINMUX_IPSR_MODSEL_DATA() instead of PINMUX_IPSR_MSEL()
 - Adjust context]
