From: Star Zeng <star.z...@intel.com>
Current UefiDpLib implementation depends on TimerLib,
as different platforms may implement and use their
own TimerLib, it makes the dp command needs to be built
by platform. The TimerLib dependency can be removed by
using performance property configuration table to make
UefiDpLib to be generic.
