powerpc: add support for MPIC message register API
Some MPIC implementations contain one or more blocks of message registers
that are used to send messages between cores via IPIs. A simple API has
been added to access (get/put, read, write, etc ...) these message registers.
The available message registers are initially discovered via nodes in the
device tree. A separate commit contains a binding for the message register
nodes.
