arch: arm: soc: add explanatory comment for kernel headers' inclusion

Browse source 
This commit adds an explanatory comment in all soc.h headers,
where kernel_includes.h header has been included, to stress out
that this header must be included after SOC-specific headers are
brought in. The reason is the fact that kernel_includes.h needs
the ARM CMSIS definitions, which are brought in by the
SOC-specific header inclusions.
