[PATCH v1 1/1] kernel.h: Split out COUNT_ARGS() and CONCATENATE()

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

kernel.h is being used as a dump for all kinds of stuff for a long time.
The COUNT_ARGS() and CONCATENATE() macros may be used in some places
without need of the full kernel.h dependency train with it.

Here is the attempt on cleaning it up by splitting out these macros().
