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.

Per our offline conversation, the LCPLL in HR2 looks to be completely
different than anything on NS/NSP/NS2 product line.  So, that will
need a new driver.  Given that this is sufficient to get the HR2 board
working, then it is acceptable to me.

Thanks,
Jon
