drivers: Replace DEV_OK by 0

Browse source 
This patch replaces all occurences of the macro DEV_OK by the actual
value 0 at the driver level. So this patch touch the files under
drivers/, include/ and samples/drivers/.

This patch is part of the effort to transition from DEV_* codes to
errno.h codes.
