Move OMAP Mailbox framework to drivers via Suman Anna <s-anna@ti.com>

Browse source 
The OMAP Mailbox driver framework is moved out of arch/arm folder
 into drivers/mailbox folder, to re-enable building it and also serve
 as a baseline for adapting to the new mailbox driver framework. The
 changes mainly contain:
   - a minor bug fix and cleanup of mach-specific mailbox code
   - remove any header dependencies from plat-omap for multi-platform
     support
   - represent mailbox device data through platform data/hwmod attrs
   - move the omap mailbox code out of plat-omap/mach-omapX to
     drivers/mailbox folder

Merge tag 'omap-for-v3.11/mailbox-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/drivers

From Tony Lindgren:

Move OMAP Mailbox framework to drivers via Suman Anna <s-anna@ti.com>

The OMAP Mailbox driver framework is moved out of arch/arm folder
into drivers/mailbox folder, to re-enable building it and also serve
as a baseline for adapting to the new mailbox driver framework. The
changes mainly contain:
  - a minor bug fix and cleanup of mach-specific mailbox code
  - remove any header dependencies from plat-omap for multi-platform
    support
  - represent mailbox device data through platform data/hwmod attrs
  - move the omap mailbox code out of plat-omap/mach-omapX to
    drivers/mailbox folder

* tag 'omap-for-v3.11/mailbox-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  mailbox/omap: move the OMAP mailbox framework to drivers
  ARM: OMAP2+: add user and fifo info to mailbox platform data
  ARM: OMAP2+: mbox: remove dependencies with soc.h
  omap: mailbox: correct the argument type for irq ops
  omap: mailbox: call request_irq after mbox queues are allocated
  omap: mailbox: check iomem resource before dereferencing it
