cpufreq: brcmstb-avs-cpufreq: add debugfs support
In order to aid debugging, we add a debugfs interface to the driver
that allows direct interaction with the AVS co-processor.
The debugfs interface provides a means for reading all and writing some
of the mailbox registers directly from the shell prompt and enables a
user to execute the communications protocol between ARM CPU and AVS CPU
step-by-step.
This interface should be used for debugging purposes only.
