[PATCH v2 0/2] gpio: i.MX: make _get_value() able to read output pin state

Make _get_value() read back the dr register instead of the psr register
when the direction is set to output. Now _get_value() can actually read
the state of an output gpio instead of being always low.

Also add a note in the migration guide file.
