dt-bindings: clock: gcc-sdm845: add sdm670 global clocks

The Snapdragon 670 clocks will be added into the sdm845 gcc driver. Most
of the new clocks, GDSCs, and resets already have reserved IDs but there
are some resources that don't. Add the new clock from Snapdragon 670 and
document the differences between the SoC parent clocks.
