pinctrl: sh-pfc: r8a7796: Fix VIN versioned groups
Versioned VIN groups can appear on different sets of pins. Using the
VIN_DATA_PIN_GROUP macro now supports proper naming of said groups
through an optional 'version' argument.
Use the 'version' argument for said macro to fix naming of versioned
groups for the R-Car M3-W R8A7796 SoC.
