remoteproc/omap: add a remoteproc driver for OMAP4
Add a remoteproc driver for OMAP4, so we can boot the dual-M3 and and DSP subsystems. Use the omap_device_* API to control the hardware state, and utilize the OMAP mailbox to interrupt the remote processor when a new message is pending (the mailbox payload is used to tell it which virtqueue was the message placed in). Conversely, when an inbound mailbox message arrives, tell the remoteproc core which virtqueue is triggered. Later we will also use the mailbox payload to signal omap-specific events like remote crashes (which will be used to trigger remoteproc recovery) and power management transitions. At that point we will also extend the remoteproc core to support this. Based on (but now quite far from) work done by Fernando Guzman Lugo <fernando.lugo@ti.com> and Hari Kanigeri <h-kanigeri2@ti.com>. Designed with Brian Swetland <swetland@google.com>.
