Subject: [PATCH v2] OMAP2: Devkit8000: Use _cansleep GPIO functions for
 display reset lines

The display reset lines are connected to a TPS65930 which may sleep
when changing GPIO values. Use the appropriate function to silence
a nasty warning from gpiolib.

Gmail destroyed the previous patch send, so resending with a sane client.
