So, that will need a new driver. Given that this is sufficient to get the HR2 board working, then it is acceptable to me.

Add support for the Broadcom Hurricane 2 SoC clock controller. We can re-use the existing iProc clock library since the SoC's architecture is largely the same as its predecessors.
