60d56333e8 ARM: bcm2835: Define two new packets from the latest firmware. 
These packets give us direct access to the firmware's power management
code, as opposed to GET/SET_POWER_STATE packets that only had a couple
of domains implemented.

This gives us a function for making mailbox property channel requests
of the firmware, which is most notable in that it will let us get and
set clock rates.
