Device-Tree bindings for MediaTek MT5896 SoC based SARADC

Required properties:
- compatible	    : Should be
			"mt5896,saradc" : for MT5896 SoC
- reg 		    : Specifies base physical address and size of the registers;


Example:

	saradc {
		compatible = "mt5896,saradc";
		interrupt-parent = <&mtk_intc2_irq_high>;
		reg = <0 0x1f020a00 0 0x200>;
		interrupts = <0x0 0x10 0x4>;
	};
