gpio: Update mcux igpio driver to use new gpio api

Browse source 
Updates the mcux igpio 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.

Removes port configuration support since that feature is deprecated in
the new gpio api.

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

On boards:
- mimxrt1015_evk
- mimxrt1020_evk
- mimxrt1050_evk
- mimxrt1060_evk
- mimxrt1064_evk
