isa: configure serial+parallel by index.
This patch adds a 'index' property to the isa-parallel and isa-serial
devices. This can be used to create devices with the default isa irqs
and ioports by simply specifying the index, i.e.
-device isa-serial,index=1
instead of
-device isa-serial,iobase=0x2f8,irq=3
for ttyS1 aka com2. Likewise for parallel ports.
