I've thought about this more, and I'd really rather not.  The list of
affected drivers is short and is not a large maintenance burden.  I
don't think a list of 2 or 3 architecture selects for each driver is
unreasonable.  A "XILINX_DRIVERS" config item doesn't really help much
anyway.  At any given time one of these drivers may be needed on
another platform.  ie. the SystemACE device is present on at least one
non-virtex, non-spartan platform.
