sam 0d93c7da52 o add a bus space tag that forces a 2usec delay between r/w ops; this is
used for the optional GPS+RS485 uarts on the Gateworks Cambria boards
  which otherwise are unreliable
o setup the hack bus space tag for the GPS+RS485 uarts
o program the gpio interrupts for the uarts to be edge-rising
o force timing on the expansion bus for the uarts to be "slow"

Thanks to Chris Lang of Gateworks for these tips.
