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.

ARM: mvebu: fix cpuidle implementation to work on big-endian systems
On Marvell Armada XP, when a CPU comes back from deep idle state of
cpuidle, it restarts its execution at armada_370_xp_cpu_resume(),
which puts back the CPU into the coherency, and then calls the generic
cpu_resume() function.
While this works on little-endian configurations, it doesn't work on
big-endian configurations because the CPU restarts in little-endian,
and therefore must be switched back to big-endian to operate
properly. To achieve this, a 'setend be' instruction must be executed
in big-endian configurations. However, the ARM_BE8() macro that is
used to implement nice compile-time conditional for ARM LE vs. ARM BE8
is not easily usable in inline assembly.
Therefore, this patch moves the armada_370_xp_cpu_resume() C function,
which was anyway just a block of inline assembly, into a proper
pmsu_ll.S file, and adds the appropriate ARM_BE8(setend be)
instruction.
Without this patch, an Armada XP big endian configuration with cpuidle
enabled fails to boot, as it hangs as soon as one of the CPU hits the
deep idle state.
