Change default for the unused signals from used FMC L/Ha/b bank?
If e.g. LA bank is used (no DISABLE_FMC_LA), but only some LA* signals are used, all other (unused) signals are by default "inout" with IO_STANDARD_VADJ, as all user defines for those signals are optional. What about making DIRECTION_* obligatory and do not generate ports for those unused signals? @tlevens ?
