Current EDMA driver is not taking care of EDMA channels/slots
which are allocated from other processor, say DSP. If a
channel/slot is allocated from DSP, the existing EDMA driver
can still allocate the same resource on ARM.
This patch enables the user to pass the channel/slots reserved
for DSP as platform data. EDMA driver scans this list during
probe and prepares a bitmap of channel/slots which can be used
on ARM side.
Trying to reserve channels by doing a 'pre-allocate' using
edma_alloc_{slot|channel}() API does not work because
1) The reservation should be done in probe() to avoid race
with other ARM side driver trying to use EDMA
2) The alloc channel API sets up the access through shadow region
0 which will be incorrect for DSP usage. It also sets up the
channel <-> queue number mapping which is not required as DSP
will likely do its own mapping anyway.
3) (minor) There is no API to allocate channels in bulk.

This patch modifies the EDMA driver to expect the channel
controller (CC) infomation passed on by the platform as a fixed
size (EDMA_MAX_CC) array of pointers to structures.
Doing so helps catch errors of the sort where the resource
structure has information for more channel controllers than
the number channel controller info structures defined.
Such insufficient platform data would lead to illegal memory
accesses.

On some Samsung SoCs not all SDHCI controllers have card detect (CD)
line. For some embedded designs it is not even needed, because ususally
the device (like SDIO flash memory or wifi controller) is permanently
wired to the controller. There are also systems which have a card detect
line connected to some of the external interrupt lines or the presence
of the card depends on some other actions (like enabling a power
regulator).
This patch adds all required changes to platform support code, so
another patch, which extends the driver with support for the new card
detection methods can be applied.

This huge patch mostly shuffles code. The spitz.c file contained terrible mess
and needed a cleanup, here it is:
1) Made every part modular, components are not built in if not selected.
2) Removed loads of preprocessor goo, mostly "#ifdef MACH_AKITA .... #endif" and
similar code. The kernel size will grow by a few kb now, but the file is much
more readable.
3) Reworked SD/CF power setting function and made it reentrant.
4) Add ISL6271A regulator support
5) Correctly register WM8750

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_*)

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.
