[v2] arm: omap2plus: GPIO cleanup

Commit Message

Igor Grinberg May 3, 2011, 3:22 p.m. UTC

use gpio_request_<one|array>() instead of multiple gpiolib calls,
remove unneeded variables, etc.

Signed-off-by: Igor Grinberg <[e-mail]>
---
Boot tested on cm-t35 and compile tested for others.

v2:     rebased on top of Tony's devel-cleanup
