Mailbox is restructured as below:

- OMAP1 and OMAP2 parts split out to mach-omap[1-2] respectively.
- struct mbx isolation
- Introduced device model
- Added class interface

Moved omap[1,2] specific parts in mach-omap[1,2]/

Here's the patch that updates DSP Gateway driver to 3.3.1, that
supports omap2 DSP. It also contains generic mailbox interface
considering IVA use on 2420, but this patch itself doesn't contain any
IVA driver.

Regarding omap2, this code is tested only on our 2420 custom board, so
feedbacks from testing on other chips / boards will be greatly
appreciated.

If an external LCD controller is in manual update mode, the DSP
must let the FB driver know when a frame should be send over the
remote framebuffer interface.

Convert dsp_mem semaphore to mutex

Replace clock.h with clk.h

This patch syncs omap's use of clock framework with the arm common
clock interface. Please use clk_enable/disable from now on, it
does what clk_use/unuse on omap used to do.

Misc changes to compile after sync with mainline
