these properties are built from information in the AMBA plug&play.
Required properties:
- name : Should be "GAISLER_GPIO" or "01_01a"
- reg : Address and length of the register set for the device
- interrupts : Interrupt numbers for this device
Optional properties:
- nbits : The number of gpio lines. If not present driver assumes 32 lines.
