493c303133 perf tools: Make CPUINFO_PROC an array to support different kernel versions 
After kernel 3.7 (commit b4b8f770eb),
/proc/cpuinfo replaces 'Processor' to 'model name'.

This patch makes CPUINFO_PROC to an array and provides two choices for
ARM, makes it compatible for different kernel version.

v1 -> v2: minor changes as suggested by Namhyung Kim:

 - Doesn't pass @h and @evlist to __write_cpudesc;
 - Coding style fix.

v2 -> v3:
  - Rebase:

43599d1f7a perf tools: Move syscall and arch specific defines from perf.h 
Into new perf-sys.h header.

The main reason is to separate system specific perf data
from perf tool stuff, so it could be used in small test
programs, as requested Peter:

  http://lkml.kernel.org/r/20140502115201.GI30445@twins.programming.kicks-ass.net

This separation makes the perf.h header more clear.
