[PATCH 3/8] tools/power x86_energy_perf_policy: rename get_msr() and put_msr() with intel prefix

[Perry Yuan]

From: Perry Yuan <Perry.Yuan@xxxxxxx>

Rename the get_msr() and put_msr() function with Intel prefix,that will
better help to differentiate with other processor msr operation.

No functional impact.
