This fixes a local merge conflict resolution done wrong locally in
arm-soc for-next. soc.h was added on a cleanup branch, but the driver
was moved and the header no longer needed.

[ .. and I did the same wrong merge, since git automatically does the
whole rename detection etc, so applying this patch from Olof - Linus ]

Pull ARM soc multiplatform enablement from Olof Johansson:
"This is a pretty significant branch. It's the introduction of the
first multiplatform support on ARM, and with this (and the later
branch) merged, it is now possible to build one kernel that contains
support for highbank, vexpress, mvebu, socfpga, and picoxcell. More
platforms will be convered over in the next few releases.
Two critical last things had to be done for this to be practical and
possible:
* Today each platform has its own include directory under
mach-<mach>/include/mach/*, and traditionally that is where a lot
of driver/platform shared definitions have gone, such as platform
data structures. They now need to move out to a common location
instead, and this branch moves a large number of those out to
include/linux/platform_data.
* Each platform used to list the device trees to compile for its
boards in mach-<mach>/Makefile.boot.
Both of the above changes will mean that there are some merge
conflicts to come (and some to resolve here). It's a one-time move
and once it settles in, we should be good for quite a while. Sorry
for the overhead."
Fix conflicts as per Olof.

Add a v7 defconfig enabling highbank, socfpga, mvebu, and vexpress
platforms and their drivers. Most other options are left to the default.
The existing individual platform defconfigs are kept for now as they are
a bit different. In some cases, the choices look pretty arbitrary and
just copied from other defconfigs.

Platform data for device drivers should be defined in
include/linux/platform_data/*.h, not in the architecture
and platform specific directories.
This moves such data out of the at91 include directories

Almost each SMP platform defines pen_release to manage booting secondary
CPUs. This of course clashes with the single zImage effort.
Add the pen_release definition to the ARM SMP code, and remove all others.
This should only be used by platforms which lack any kind of CPU power
management...

This adds a 'struct smp_operations' to abstract the CPU initialization
and hot plugging functions on SMP systems, which otherwise conflict
in a multiplatform kernel. This also helps shmobile and potentially
others that have more than one method to do these.
To allow the kernel to continue building, the platform hooks are
defined as weak symbols which are overrided by the platform code.
Once all platforms are converted, the "weak" attribute will be
removed and the function made static.
Unlike the original version from Marc, this new version from Arnd
does not use a generalized abstraction for per-soc data structures
but only tries to solve the problem for the SMP operations. This
way, we can collapse the previous four data structures into a
single struct, which is less systematic but also easier to follow
as a causal reader.

Since the dtb targets have moved to arch/arm/boot/dts/Makefile, sweep
the platforms that have had new targets added recently and move them over.
While I was at it, I also made the dtb generation more generic, i.e. if
the platform is enabled then all dtbs for that platform will be created.

into next/multiplatform
Enable initial ARM multi-platform support for highbank, mvebu,
socfpga, picoxcell, and vexpress.
Multi-platform support is dependent on mach/gpio.h removal and
restructuring of DEBUG_LL and dtb build rules included in this branch.
This has been built for all defconfigs, and booted on highbank with
all 5 platforms enabled.

This lets us build a multiplatform kernel for experimental purposes.
However, it will not be useful for any real work, because it relies
on a number of useful things to be disabled for now:
* SMP support must be turned off because of conflicting symbols.
Marc Zyngier has proposed a solution by adding a new SOC
operations structure to hold indirect function pointers
for these, but that work is currently stalled
* We turn on SPARSE_IRQ unconditionally, which is not supported
on most platforms. Each of them is currently in a different
state, but most are being worked on.
* A common clock framework is in place since v3.4 but not yet
being used. Work on this is on its way.
* DEBUG_LL for early debugging is currently disabled.
* THUMB2_KERNEL does not work with allyesconfig because the
kernel gets too big
[Rob Herring]: Rebased to not be dependent on the mass mach header rename.
As a result, omap2plus, imx, mxs and ux500 are not converted. Highbank,
picoxcell, mvebu, and socfpga are converted.

In preparation to support multi-platform kernels, move all the dtb targets
out of the mach Makefile.boot and into the arch/arm/boot/dts/Makefile
which is closer to the sources.
DTBs are only built when CONFIG_OF is enabled and now use top level
CONFIG_ARCH_xxx instead of chip or board specific config options.
