[PATCH v3 22/27] ARM: dts: am437x: Fix NAND device nodes

Add compatible id, GPMC register resource and interrupt
resource to NAND controller nodes.
The GPMC driver now implements gpiochip and irqchip so
enable gpio-controller and interrupt-controller properties.
With this the interrupt parent of NAND node changes so fix it
accordingly.
