This series adds support for hisilicon stub clock driver. On hi6220,
the bootloader needs load the firmware image and set info for OPPs;
after run into kernel, the stub clock driver is used to communicate
w/t firmware for cpu dynamic frequency scaling. So finally s/w will
simply write request in sram and send ipc to power controller.
These patches have been tested on 96board hikey and will be used by
cpufreq driver.
