[PATCH 1/2] perf tools: fix a typo of a Power7 event name

[Runzhen Wang]

In the Power7 PMU guide:
https://www.power.org/documentation/commonly-used-metrics-for-performance-analysis/
PM_BRU_MPRED is referred to as PM_BR_MPRED.

This patch fix the typo by changing the name of the event in kernel and
documentation accordingly.
