With kexec-based kernel boot loader on Zaurus, the machine ID is
actually correctly passed, and head-sharpsl.S is not necessary.
Introduce PXA_SHARPSL_DETECT_MACH_ID, and include head-sharpsl.S
only when that's explicitly enabled.

With a correct dev->dma_mask before calling dmabounce_register_dev(),
dma_needs_bounce() is not necessary.
The sa1111, though, is a bit complicated. Until it's fully understood
and fixed, dma_needs_bounce() for sa1111 is kept if CONFIG_SA1111 is
enabled with no side effect (with the condition of machine_is_*)
Thanks for Mike Rapoport to fix one error in the original version of
the patch and get this tested.

Not tested and enabled on MMP at this moment, and since the IRQ
is different from mach-pxa, I'd prefer to move the PMU device
back into mach-pxa/. Will introduce the PMU device to MMP once
it's enabled and tested.

With this patch, you'll get the following sysfs directories. This
structure implies that a single platform device, "omap2-mailbox" holds
multiple logical mbox instances. This could be the base to add sysfs
files for each logical mboxes. Then userland application can access a
mbox through sysfs entries if necessary(ex: setting kfifo size
dynamically)
~# tree -d -L 2 /sys/devices/platform/omap2-mailbox/
/sys/devices/platform/omap2-mailbox/
|-- driver -> ../../../bus/platform/drivers/omap2-mailbox
|-- mbox
| |-- dsp <- they are each instances of logical mailbox.

The underlying buffering implementation of mailbox
is converted from block API to kfifo due to the simplicity
and speed of kfifo.
The default size of the kfifo buffer is set to 256 bytes.
This value is configurable at compile time (via
CONFIG_OMAP_MBOX_KFIFO_SIZE), and can be changed at
runtime (via the mbox_kfifo_size module parameter).

when blk_get_request fails to get the request it is returning
without read the message from the mailbox fifo, then when it
leaves the isr and interruption is trigger again and again and
the workqueue which get elements from the request queue is never
executed and the kernel is stuck and shows a softlockup message.
Now the mailbox interrupt is disabled when request queue is full
and enabled when it pop a elememt form the request queue.

Additionally, update some of the CHIP_GE_* macros to use other
