[RFC PATCH 1/9] ARM: prepare arch/arm/platforms for immigration

At the point of v4.6-rc1, we have 71 mach-* directories in arch/arm/
and 42 of them do not have either Makefile.boot or an SoC header
directory (mach-*/include/mach).  In other words, 60 % of mach-*
directories lost reason to sit there.  We expect more SoCs will do
as the progress of Multi-platform conversion.

This commit creates a new home "arch/arm/platforms/" for such SoCs,
where we can use the standard Makefile notation "obj-y" instead of
the ARM special one "machine-y".
