[PATCH 00/15] omap: mailbox: reorganize init

Hi,

The main purpose of this patch series is to be able to compile mach platform
data as built-in. Otherwise, client modules such as bridgedriver will load the
platform code, but not the mach code when mailbox is built as a module.

Unfortunately, there's no easy way to do that since plat and mach code are
deepely interrelated. So the first patches try to separate the mailbox
registering through a defined omap_mbox_platform_data.

Also, it's worth noting that mailboxes are not a one-to-one mapping to
resources; that is, some resources belong to multiple mboxes. So it's best to
think of mailboxes as fake devices. That is why custom platform_data is required.

Finally, a bunch of cleaning up is done in the very first patches, specially for
OMAP1.

The initial RFC included comments from Felipe Balbi, and this proposal includes
comments from Tony Lindgren.

Tested on OMAP3 (beagleboard), and compiled-tested for OMAP1.
