[PATCH 2/2] perf vendor events arm64: Fix Tegra410 Olympus event 0x0197

The name and description for NVIDIA Tegra410 Olympus implementation-defined
event 0x0197 incorrectly indicate a TXREQ limit between one quarter and
one half. Correct them to describe a TXREQ limit below one half.

Fixes: 86ff690f45cc ("perf vendor events arm64: Add Tegra410 Olympus PMU events")
