It seems to me the GPIOF_DIR_XXX are defined in linux/gpio.h. It would
be nice to refer to these flags when interpreting the return value
from the bd70528_get_direction (used in bd70528_gpio_get) - and actually
it might be nice to use those as a return value from bd70528_get_direction.

But I'll go with raw values for now and leave possible definition
moving/header refactoring to you who know the direction of code better :)
