PCI_DOMAINS config should be selected for any SoCs
having more than a single PCIe controller. Without PCI_DOMAINS
config, only one PCIe controller gets registered.
Select PCI_DOMAINS in ARCH_MULTIPLATFORM if PCI is selected, since
it doesn't harm even if a platform has a single PCIe port.
Also remove PCI_DOMAINS being selected from other platform
specific configs.

Many ARM sub-architectures use prompts followed by "if" conditional,
but it is wrong.
Please notice the difference between
config ARCH_FOO
bool "Foo SoCs" if ARCH_MULTI_V7
and
config ARCH_FOO
bool "Foo SoCs"
depends on ARCH_MULTI_V7
These two are *not* equivalent!
In the former statement, it is not ARCH_FOO, but its prompt that
depends on ARCH_MULTI_V7. So, it is completely valid that ARCH_FOO
is selected by another, but ARCH_MULTI_V7 is still disabled. As it is
not unmet dependency, Kconfig never warns. This is probably not what
you want.
The former should be used only when you need to do so, and you really
understand what you are doing. (In most cases, it should be wrong!)
For enabling/disabling sub-architectures, the latter is always correct.
As a good side effect, this commit fixes some entries over 80 columns
(mach-imx, mach-integrator, mach-mbevu).
[Arnd: I note that there is not really a bug here, according to
the discussion that followed, but I can see value in being consistent
and in making the lines shorter]

The System Type menu is getting quite long with platforms and is
inconsistent in handling of sub-arch specific options. Tidy up the menu
by making platform options a menuconfig entry containing any platform
specific config items.

When targetting ARCH_MULTIPLATFORM, we may include support for SoCs with
PCI-capable devices (e.g. mach-virt with virtio-pci).
This patch allows PCI support to be selected for these SoCs by selecting
CONFIG_MIGHT_HAVE_PCI when CONFIG_ARCH_MULTIPLATFORM=y and removes the
individual selections from multi-platform enabled SoCs.

The cns3xxx is an ARM11MPCore which has all the V6K extensions, so V6K
should be selected instead. Dropping the select will use the default for
ARCH_MULTI_V6 which is V6K.

MULTI_V6 should default to V6K as it is more optimal than V6. Any
platform which is not V6K should select CPU_V6 which will enable the
less optimal code paths.

This adds very minimal support for booting cns3xxx using a device
tree. It should support the same devices that cns3420vb provides
but gets them from the DT. All devices that don't have their own
binding are probed through auxdata. This is completely untested
and likely incomplete.
Booting through ATAGS is made optional, so it can be turned off
by anybody who has a DTB file.

This moves the cns3xxx configuration option inside of ARCH_MULTIPLATFORM,
since there is no reason for not doing it now. We can then also remove
the three header files that become obsolete.
