Drop the old geode_gpio crud, as well as the raw outl() calls; instead, use the Linux GPIO API where possible, and the cs5535_gpio API in other places. Note that we don't actually clean up the driver properly yet (once loaded, it always remains loaded). That'll come later.. This patch is necessary for building the driver.
