gpiolib: Make use of enum gpio_lookup_flags consistent
The library uses enum gpio_lookup_flags to define the possible
characteristics of GPIO pin. Since enumerator listed only individual
bits the common use of it is in a form of a bitmask of
gpio_lookup_flags GPIO_* values. The more correct type for this is
unsigned long.
Due to above convert all users to use unsigned long instead of
enum gpio_lookup_flags except enumerator definition.
While here, make field and parameter descriptions consistent as well.
