gpio: Update imx gpio driver to use new gpio api

Updates the imx gpio driver and all associated boards to use new
device tree compatible gpio configuration flags. Implements new port
get/set/clear/toggle and pin_interrupt_configure functions recently
added to the gpio api.

Assumes the gpio api layer handles translating logical flags to physical
flags.

Tested with:
- samples/basic/blinky
- samples/basic/button
- tests/drivers/gpio/gpio_api_1pin
- tests/drivers/gpio/gpio_basic_api

On boards:
- udoo_neo_full_m4
