ARM TrustZone Address Space Controller TZC-380
----------------------------------------------

Required properties:
- compatible: "arm,tzc380"
- reg:        base address (depending on SoC) and length (usually 0x4000) of
	      device registers.
- interrupts: external interrupt line number and interrupt sense mode of the
	      interrupt line signaling in case of an invalid memory access.

Examples:
configured and enabled:
tzasc@021d0000 { /* TZASC1 */
	compatible = "arm,tzc380";
	reg = <0x021d0000 0x4000>;
	interrupts = <0 108 IRQ_TYPE_LEVEL_HIGH>;
};

configured but disabled:
tzasc@021d4000 { /* TZASC2 */
	compatible = "arm,tzc380";
	reg = <0x021d4000 0x4000>;
	interrupts = <0 109 IRQ_TYPE_LEVEL_HIGH>;
	status = "disabled";
};
