From: Felipe Contreras <felipe.contreras@xxxxxxxxx>
Remove static platform_device and resource data within
omap mailbox driver; use the one defined in the hwmod
database along with omap_device framework for device
build and registration.
Add device latency functions to be used, so clock can be
enabled and sysconfig is configured.
