ARM: OMAP: switch to gpio_direction_output

More conversion to the standard GPIO interfaces:  stop using
omap_set_gpio_direction() entirely, and switch over to the
gpio_direction_output() call.

Note that because gpio_direction_output() includes the initial
value, this change isn't quite transparent.

 - For the call sites which defined an initial value either
   before or after setting the direction, that value was used.

   When that value was previously assigned afterwards, this
   could eliminate a brief output glitch ... and possibly
   change behavior.  In a few cases (LCDs) several values
   were assigned together ... those were re-arranged to match
   the explicit sequence provided.

 - Some call sites didn't define such a value; so I chose an
   initial "off/reset" value that seemed to default to "off".

In short, files touched by this patch might notice some small
changes in startup behavior (with trivial fixes).
