Merge "Broadcom Cygnus SoC Device Tree changes" from Florian Fianelli:

This patchset contains initial support for Broadcom's Cygnus SoC based on our
iProc architecture. Initial support is minimal and includes just the mach
platform code, clock driver, and a basic device tree configuration. Peripheral
drivers will be submitted soon, as will device tree configurations for other
Cygnus board variants.

These are the Device Tree changes
