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.
