This patch series adds device tree support for the Broadcom Northstar,
Northstar Plus, and Northstar 2 clocks.  This is being sent as a
separate patch series due to the the clk maintainer(s) not wanting to
pull in device tree changes into the clk repo.  This series is an RFC
due to a potential merge "race" between the device tree changes and the
clk changes.  If the device tree changes go in before the clk changes,
there is a window where there are non-working clk entries in the device
tree.  So, these patches will be officially pushed once the clk changes
are merged.

Thanks,
Jon
