clk: cygnus: add clock support for Broadcom Cygnus
The Broadcom Cygnus SoC is architected under the iProc architecture. It
has the following PLLs: ARMPLL, GENPLL, LCPLL0, MIPIPLL, all dervied
from an onboard crystal. Cygnus also has various ASIU clocks that are
derived directly from the onboard crystal.
