The TWD and SCU configs are selected by default as long as
MSM_SCORPIONMP is false and/or MCT is false. Implementing the
logic this way certainly saves lines in the Kconfig but it
precludes those machines which select MSM_SCORPIONMP or MCT from
participating in the single zImage effort because when those
machines are combined with other SMP capable machines the TWD and
SCU are no longer selected by default.
Push the select out to the machine entries so that we can compile
these machines together and still select the appropriate configs.

This series enables multiplatform support on the SIRF prima2/marco/atlas6
platform. The code was already quite tidy, so this is a relatively simple
change, and it follows similar changes we made to other ARMv7 based
platforms recently.
* prima2/multiplatform:
ARM: sirf: enable support in multi_v7_defconfig
ARM: sirf: enable multiplatform support
ARM: sirf: use clocksource_of infrastructure
ARM: sirf: move debug-macro.S to include/debug/sirf.S
ARM: sirf: enable sparse IRQ
ARM: sirf: move irq driver to drivers/irqchip
ARM: sirf: fix prima2 interrupt lookup
pinctrl: sirf: convert to linear irq domain
clocksource: make CLOCKSOURCE_OF_DECLARE type safe
ARM/dts: prima2: add .dtsi for atlas6 and .dts for atla6-evb board
arm: prima2: add new SiRFatlas6 machine in common board
ARM: smp_twd: convert to use CLKSRC_OF init
clocksource: tegra20: use the device_node pointer passed to init
clocksource: pass DT node pointer to init functions
clocksource: add empty version of clocksource_of_init

The hotplug.c file uses assembly instructions that are only available
on ARMv7 but not on ARMv6. This is ok because we know that code will
only run on arm ARMv7 SPEARr13xx, but it produces build errors when
we also enable one of the ARMv6 targets in a multiplatform configuration.

This replaces an earlier patch from Viresh Kumar to move
the spear platform over to the generic DMA binding. This
version is now based on the merged multiplatform capable
spear platform, rather than the separate spear13xx/3xx/6xx
directories.

We can now enable mach-spear without selecting any of the
machines in a multiplatform configuration.
Doing so causes a build error that is trivial to fix by
making both the spear13xx and the spear3xx/6xx portion of
this file conditional rather than alternatives.

The spear platform is now multiplatform capable in principle,
and everything still builds when enabled. This slightly rearranges
the Kconfig options for spear to enable both single- and multiplatform
support. As a side-effect, even building the single spear kernel
can now enable spear3xx and spear6xx simultaneously, although
not together with spear13xx, because they are a different archicture
version (v7 instead of v5).

Both spear3xx and spear6xx have a global symbol named
pl080_plat_data. Eventually, both should be removed, but
for now, we can rename one to pl080_plat_data and declare
it static, since that one does not actually need to be
visible outside of spear6xx.c.

Device drivers should not access MMIO registers through hardcoded
platform specific address constants. Instead, we can pass the
MMIO token to the spear clock driver in the initialization routine
to contain that knowledge in the platform code itself.
Ideally, the clock driver would use of_iomap() or similar to
get the address, and that can be used later, but for now, this
is the minimal change.

No file outside of mach-spear includes these files any more,
so they don't have to be globally visible now.

There are no conflicting files between the three mach-spear* directories
and plat-spear any more, so we can now move all file to a common
mach-spear directory.
