The HIP04 driver only targets a single CPU at a time, even if
the notional affinity is wider. Let's inform the core code
about this.

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]

hisi has a general dependency on ARCH_MULTIPLATFORM, which is
problematic when building a kernel for non-V7 platforms but selecting
drivers that might conflict with other architecture levels.
In this case, it broke my (still out of tree) patch set that
enables V7M multiplatform support, since that does not enable
MULTI_IRQ support:
arch/arm/kernel/built-in.o: In function `set_handle_irq':
arch/arm/kernel/irq.c:125: undefined reference to `handle_arch_irq'
arch/arm/kernel/built-in.o: In function `setup_arch':
arch/arm/kernel/setup.c:965: undefined reference to `handle_arch_irq'
Since all hisilicon platforms are ARMv7 based, we can avoid this
problem by just making the dependency more specific.

Enable support for the Hisilicon HiX5HD2 SoC. This HiX5HD2 SoC series
support both single and dual Cortex-A9 cores.
Add ARCH_HIX5HD2 to distinguish HiX5HD2 from Hi3xxx.
They are different in implementation such as SMP, IPs integarted and
earlycon configure.

Since some new Hisilicon SoCs are not named as hi3xxx, rename mach-hi3xxx
to mach-hisi instead. And the pronounciation of "hisi" is similar to the
chinese pronounciation of Hisilicon. So Hisilicon guys like this name.
ARCH_HI3xxx will be renamed later since other drivers are using it and
they are still in linux-next git tree. So rename ARCH_HI3xxx later.
