pinctrl: sh-pfc: Add optional arg to VIN_DATA_PIN_GROUP
VIN data groups may appear on different sets of pins, usually named "vinX_data_[a|b]". The existing VIN_DATA_PIN_GROUP() does not support appending the '_a' or '_b' suffix, leading to the definition of group names not consistent with the ones defined using the SH_PFC_PIN_GROUP() macro. Fix this by making the VIN_DATA_PIN_GROUP macro a variadic one, which accepts an optional 'version' argument.
