mediatek: add support for the new MT7623 Arm SoC

the support is still WIP. next steps are to make the pmic and ethernet work.
this is the first commit to make sure nothing gets lost.

++* Mediatek Thermal
++
++This describes the device tree binding for the Mediatek thermal controller
++which measures the on-SoC temperatures. This device does not have its own ADC,
++instead it directly controls the AUXADC via AHB bus accesses. For this reason
++this device needs phandles to the AUXADC.
++
++Required properties:
++- compatible: "mediatek,mt8173-thermal"
++- reg: Address range of the thermal controller
++- interrupts: IRQ for the thermal controller
++- clocks, clock-names: Clocks needed for the thermal controller. required
++                       clocks are:
++		"therm":	Main clock needed for register access
++		"auxadc":	The AUXADC clock
++- resets, reset-names: Reference to the reset controller controlling the thermal
++                       controller. Required reset-names:
++		"therm":	The main reset line
++- auxadc: A phandle to the AUXADC which the thermal controller uses
++- apmixedsys: A phandle to the APMIXEDSYS controller.
++- #thermal-sensor-cells : Should be 1. See ./thermal.txt for a description
++
++Example:
++
++	thermal: thermal@1100b000 {
++		#thermal-sensor-cells = <1>;
++		compatible = "mediatek,mt8173-thermal";
++		reg = <0 0x1100b000 0 0x1000>;
++		interrupts = <0 70 IRQ_TYPE_LEVEL_LOW>;
++		clocks = <&pericfg CLK_PERI_THERM>, <&pericfg CLK_PERI_AUXADC>;
++		clock-names = "therm", "auxadc";
++		resets = <&pericfg MT8173_PERI_THERM_SW_RST>;
++		reset-names = "therm";
++		auxadc = <&auxadc>;
++		apmixedsys = <&apmixedsys>;
++	};
