In the QE, a few GPIOs have an associated IRQ to notify changes.
Add IRQ support to QE GPIO.

As not all GPIOs have an associated IRQ, the driver needs to know
to which GPIO corresponds each provided IRQ. This is provided via
multiple compatible properties:

	compatible = "fsl,mpc8323-qe-pario-bank-a"
	compatible = "fsl,mpc8323-qe-pario-bank-b"
	compatible = "fsl,mpc8323-qe-pario-bank-c"

	compatible = "fsl,mpc8360-qe-pario-bank-a"
	compatible = "fsl,mpc8360-qe-pario-bank-b"
	compatible = "fsl,mpc8360-qe-pario-bank-c"
	compatible = "fsl,mpc8360-qe-pario-bank-d"
	compatible = "fsl,mpc8360-qe-pario-bank-e"
	compatible = "fsl,mpc8360-qe-pario-bank-f"
	compatible = "fsl,mpc8360-qe-pario-bank-g"

	compatible = "fsl,mpc8568-qe-pario-bank-a"
	compatible = "fsl,mpc8568-qe-pario-bank-b"
	compatible = "fsl,mpc8568-qe-pario-bank-c"
	compatible = "fsl,mpc8568-qe-pario-bank-d"
	compatible = "fsl,mpc8568-qe-pario-bank-e"
	compatible = "fsl,mpc8568-qe-pario-bank-f"

When not using IRQ and for banks having no IRQ (like bank D on mpc8323)
the origin compatible = "fsl,mpc8323-qe-pario-bank" is still valid.
