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.

[AD: keep CMUs in google,gs101.h sorted alphabetically, and resolve
minor merge conflicts in google,gs101-clock.yaml]
