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).
