[PULL 02/11] trace-events: remove the remaining vcpu trace events

From: Alex Bennée <alex.bennee(a)linaro.org&gt; While these are all in helper functions being designated vcpu events complicates the removal of the dynamic vcpu state code. TCG plugins allow you to instrument vcpu_[init|exit|idle]. We rename cpu_reset and make it a normal trace point.
