[0/3] arm64: zynqmp: Add thermal zones

At the moment, the ZynqMP Analog Monitoring System (AMS) is only used
sporadically. As it is built into the SoC and doesn't depend on external
hardware, it can be exposed to userspace for all boards. Additionally,
we can use it to implement thermal zones.

  arm64: zynqmp: Enable AMS for all boards
  arm64: zynqmp: Expose AMS to userspace as HWMON
