70997d88c4 arm: rpi: Add a file to handle messages
The bcm283x chips provide a way for the ARM core to communicate with the
graphics processor, which is in charge of many things. This is handled by
way of a message prototcol.

At present the code for sending message (and receiving a reply) is spread
around U-Boot, primarily in the board file. This means that sending a
message from a driver requires duplicating the code.

Create a new message implementation with a function to support powering on
a subsystem as a starting point.
