stream synchronization during capture and playback usecases.

Required properties:
- reg : physical address and length of avtimer register
- reg-names : AVtimer register name
  Required register resource entries are:
  "avtimer_lsb_addr" : AVtimer lsb physical address
  "avtimer_msb_addr" : AVtimer msb physical address
- compatible : Must be "qcom,avtimer"

Example:
	qcom,avtimer {
		compatible = "qcom,avtimer";
		reg = <0xfe053008 0x4>,
			<0xfe05300c 0x4>;
		reg-names = "avtimer_lsb_addr", "avtimer_msb_addr";
	};
