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.

This collides with André's work adding HSI0. Perhaps combine the series 
or even the patches and just send clocks as a series. Then it is clear 
who should merge it.

I'll add Peter's clock-related HSI2 patches into my HSI0 series, which will
avoid more merge conflicts.
