dt-bindings: thermal: Describe Armada AP806 and CP110

Required properties:

- compatible: Should be set to one of the following:

		marvell,armada370-thermal

		marvell,armada375-thermal

		marvell,armada380-thermal

		marvell,armadaxp-thermal

    * marvell,armada370-thermal

    * marvell,armada375-thermal

    * marvell,armada380-thermal

    * marvell,armadaxp-thermal

    * marvell,armada-ap806-thermal

    * marvell,armada-cp110-thermal

- reg: Device's register space.

		Two entries are expected, see the examples below.

		The first one is required for the sensor register;

		the second one is required for the control register

		to be used for sensor initialization (a.k.a. calibration).

  Two entries are expected, see the examples below. The first one points

  to the status register (4B). The second one points to the control

  registers (8B).

  Note: The compatibles marvell,armada370-thermal,

  marvell,armada380-thermal, and marvell,armadaxp-thermal must point to

  "control MSB/control 1", with size of 4 (deprecated binding), or point

  to "control LSB/control 0" with size of 8 (current binding). All other

  compatibles must point to "control LSB/control 0" with size of 8.
