[PATCH 2/6 -tip] perf stat: treat same behaviour for all CYCLES and CLOCKS

[Jaswinder Singh Rajput <jaswinder@kernel.org>]

For normalization also added SW_CPU_CLOCK and HW_BUS_CYCLES

For nsec_printout also added SW_CPU_CLOCK

Added helper functions to check counter unit as cycles and instructions
