serial: mxs-auart: replace hardcoded 1 with predefined macro GPIO_LINE_DIRECTION_IN

Browse Source 
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.
