Add an rpmsg driver sample, which demonstrates how to communicate with an AMP-configured remote processor over the rpmsg bus. Note how once probed, the driver can immediately start sending messages using the rpmsg_send() API, without having to worry about creating endpoints or allocating rpmsg addresses: all that work is done by the rpmsg bus, and the required information is already embedded in the rpmsg channel that the driver is probed with. In this sample, the driver simply sends a "Hello World!" message to the remote processor repeatedly. Designed with Brian Swetland <swetland@google.com>.
