There is no need for a separate common OMAP mailbox module now that the OMAP1 mailbox driver has been removed. So, consolidate the two individual OMAP mailbox modules into a single driver. This streamlines the driver for converting to mailbox framework. The following are the main changes: - collapse mailbox-omap2.c into omap-mailbox.c - remove omap_mbox_ops and replace the ops calls with the equivalent functionality. - simplify the sub-mailbox startup/shutdown functionality, the one-time operations are moved into probe, and the pm_runtime_get_sync and pm_runtime_put_sync can be invoked without using a configuration counter. - move all definitions from private omap_mbox.h into the source code, and eliminate this internal header. - rename some variables that used the omap2_mbox prefix with a generic omap_mbox prefix.
