Not all the channels and slots available on the DM646x EVM
are used by the devices on the EVM. These resources can be
used by the DSP to speed up codec operations.

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.

This patch helps get rid of the following sparse warnings
of the type:

  CHECK   arch/arm/mach-davinci/da830.c
arch/arm/mach-davinci/da830.c:1026:3: warning: Initializer entry defined twice
arch/arm/mach-davinci/da830.c:1027:3:   also defined here

coming from the irq priorities array init.

Apart from one instance of genuinie repetition, most are are instances
of multiple #defines of the same interrupt number. I have not
removed the multiple definitions from the irq.h file in the hope
that someone might decide to use them as shared interrupts at some
point of time. The priority initialization however needs to be done
only once and hence has been corrected.

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.
  |   |-- ducati
  |   |-- iva2
  |   |-- mbox01
  |   |-- mbox02
  |   |-- mbox03

  |-- power
  `-- subsystem -> ../../../bus/platform

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).
