arm64/include/asm/dma-contiguous.h is trying to include
<asm-genric/dma-contiguous.h> which does not exist, and thus failing
build for arm64 if we enable CONFIG_DMA_CMA. This patch fixes build
error by removing unwanted header inclusion from arm64's dma-contiguous.h.

arm64 bit targets need the features CMA provides. Add the appropriate
hooks, header files, and Kconfig to allow this to happen.

The <linux/device.h> header includes a lot of stuff, and
it in turn gets a lot of use just for the basic "struct device"
which appears so often.

Clean up the users as follows:

1) For those headers only needing "struct device" as a pointer
in fcn args, replace the include with exactly that.

2) For headers not really using anything from device.h, simply
delete the include altogether.

3) For headers relying on getting device.h implicitly before
being included themselves, now explicitly include device.h

4) For files in which doing #1 or #2 uncovers an implicit
dependency on some other header, fix by explicitly adding
the required header(s).

Any C files that were implicitly relying on device.h to be
present have already been dealt with in advance.

Total removals from #1 and #2: 51.  Total additions coming
from #3: 9.  Total other implicit dependencies from #4: 7.

As of 3.3-rc1, there were 110, so a net removal of 42 gives
about a 38% reduction in device.h presence in include/*

Add support for the irq controller in Qualcomm 8xxx pmic. The 8xxx
interrupt controller provides control for gpio and mpp configured as
interrupts in addition to other subdevice interrupts. The interrupt
controller also provides a way to read the real time status of an
interrupt. This real time status is the only way one can get the
input values of gpio and mpp lines.

Add support for the Qualcomm PM8921 PMIC chip. The core driver
will communicate with the PMIC chip via the MSM SSBI bus.

Migrating to clkdev has several advantages:

 * Less code in mach-msm/clock.c

 * A more robust clk_get() implementation

 * clk_add_alias() support

 * clk_get_sys() support

In general, this will help board authors setup clock aliases and
break the dependency on device pointers in the clock tables.

This allows us to use smp_cross_call() to trigger a number of different
software generated interrupts, rather than combining them all on one
SGI.  Recover the SGI number via do_IPI.

The existing MSM irq entry macro is specific to a VIC
implementation. Renaming this makes room for irq support based on
other interrupt controllers.

Qualcomm development of the MSM SOC framebuffer driver has
diverged significantly from the driver used by Android. This
is a snapshot of our current driver, in all it's agony. We are
putting this in staging to help with the process of converging
the two drivers.

At this point, the driver has been tested only in dumb
framebuffer mode.
