pinctrl: sh-pfc: r8a7791/r8a7793: Correct SCIFB1_B SCK MOD_SEL value
When using serial port SCIFB1_B, transmit works, but nothing is
received.
Receive fails because the SCIFB1_SCK_B settings configure the wrong
value for the sel_scifb1 field in the Module Select Register (MOD_SEL),
due to an ambiguity in the R-Car M2-W and M2-N datasheets.
Tested on r8a7791/koelsch using pins 53 (TXD) and 72 (RXD) on EXIO
Connector A.
