dt-bindings: clock: google,gs101-clock: add HSI2 clock management unit

Browse Source 
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
     * resolve minor merge conflicts in google,gs101-clock.yaml
     * s/ufs_embd/ufs    s/mmc_card/mmc
