[PATCH 1/2] gpio: correct docs about return value of gpiod_get_direction

[Wolfram Sang <wsa@xxxxxxxxxxxxx>]

From: Wolfram Sang <wsa+renesas@xxxxxxxxxxxxxxxxxxxx>

The use of the GPIOF_* flags is deprecated, so don't advertise them
here. Document the plain numbers for now until we have a better
solution.
