i2c: Compare the return value of gpiod_get_direction against GPIO_LINE_DIRECTION_OUT

The GPIO_LINE_DIRECTION_* definitions have just recently been exposed to
gpio consumers.h by breaking them out in a separate defs.h file.

Use this to validate the gpio direction instead of the hard-coded literal.
