From: Peter Griffin <peter.griffin@linaro.org>

Add dt schema documentation and clock IDs for the High Speed Interface
2 (HSI2) clock management unit. This CMU feeds high speed interfaces
such as PCIe and UFS.

minor merge conflicts in google,gs101-clock.yaml]

I wonder whether we can get rid of the _embd and _card.
