omap mailbox: Set a device in logical mbox instance for traceability
With this patch, you'll get the following sysfs directories. This
structure implies that a single platform device, "omap2-mailbox" holds
multiple logical mbox instances. This could be the base to add sysfs
files for each logical mboxes. Then userland application can access a
mbox through sysfs entries if necessary(ex: setting kfifo size
dynamically)
