defconfig: arm64: msm-perf: Enable MSM_TZ_LOG

The tz_log driver is responsible for allocating the memory for the
'qsee_log' buffer. If tz_log driver is disabled and some part of the
bootchain has set the qsee_log address before Linux booted, then that
previous address will continue being used. If that address overlaps
with memory used for some other purpose, logging to qsee_log may
scribble on memory and cause a crash.
