Subject: [PATCH v2 0/2] drivers: mailbox: omap-mailbox out of plat code

As part of plat-omap code cleanup, move omap-mailbox framework to
a newly drivers/mailbox folder, right now this code is specific to
OMAP platforms, but with some clean up it could be the base for a
generic framework; living under drivers/mailbox could give it some
exposure for interested developers to give feedback and propose changes.

In the past there was a mailbox-like driver in mach-ux500, I was
hoping both could live under the same folder, however the platform
using it, was dropped a couple of kernel releases back and with it the
other similar mailbox implementation.

However and as per Loic's comments[1], it looks like there could be
another potential mailbox candidate to live under drivers/mailbox in the
works, along with some proposed changes that could make the original
framework to evolve towards a generic implementation.

So for now, lets move the mailbox code to drivers/mailbox and split
internal structures from common API for others to use.

Based on 3.7-rc4.
