* port libgpio to am335x. * increase NR_IRQ to 16 to avoid too many IRQs requested error. * move gpio binary to /sbin (that's where mount looks for drivers). * fix bug that re-enabled banks that were disabled due to bad revision. * fix padconf masks for dm37xx in gpio driver (should be 16-bit). * fix a few typos in README.txt and comments.
