Subject: [PATCH 1/2] Get CPU MHz on RISC-V

This test needs to know current CPU MHz value to output test results correctly.
This patch set a CPU MHz value in case of using RISC-V arch.

get_cpu_mhz() tries to acquire CPU MHz value from /proc/cpuinfo for
some arches. It is not possible to get CPU MHz value from
/proc/cpuinfo on RISC-V. It returns always 0. But it is possible to
get this value calculated on cpu cycles. Use CPU cycles value calculated
in sample_get_cpu_mhz();

This patch is tested on SiFive HiFive Unmatched board.
