The Luminary variant of the PL061 has registers GPIOPUR and GPIOPDR which lets the guest configure whether the GPIO lines are pull-up, pull-down, or truly floating. Instead of assuming all lines are pulled high, honour the PUR and PDR registers. For the plain PL061, continue to assume that lines have an external pull-up resistor, as we did before. The stellaris board actually relies on this behaviour -- the CD line of the ssd0323 display device is connected to GPIO output C7, and it is only because of a different bug which we're about to fix that we weren't incorrectly driving this line high on reset and putting the ssd0323 into data mode.
