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.
