The Xilinx AMS includes an ADC as well as on-chip sensors that can be
used to sample external and monitor on-die operating conditions, such as
temperature and supply voltage levels.

The patch series [0] for the AMS driver was applied, but the patch to
add the node to the device tree was skipped. Thus, the driver is not
probed at all.
I added the xilinx_ams node to zynqmp-clk-ccf.dtsi, too, to allow the
driver to find the firmware clock as mentioned in my review comment on
the previous series.
