ARM: initial multiplatform support
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.

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.

ARM: initial multiplatform support
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.
