dt-bindings: clock: google,gs101-clock: add HSI0 clock management unit
Add dt-schema documentation and clock IDs for the high speed interface
0 HSI0 clock management unit. This is used (amongst others) for USB.
While the usual (sed) script has been used to derive the linux clock
IDs from the data sheet, one manual tweak was applied to fix a typo
which we don't want to carry:
HSI0_USPDPDBG_USER -> HSI0_USBDPDBG_USER (note USB vs USP).
