eric miao 7a26d3a33f [ARM] pxa: generalize the muxed gpio IRQ handling code with loop and ffs()
1. As David Brownell suggests, using ffs() is going to make the loop
   a bit faster (by avoiding unnecessary shift and iteration)

2. Russell suggested find_{first,next}_bit() being used with the
   gedr[] array
