OMAP: mailbox: build device using omap_device/omap_hwmod

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.
