Chun-Min Chang e1d94bc620 Bug 1891458 - Update arm-cpu-runtime-detection patch r=media-playback-reviewers,padenot
The aarch64_cpudetect.c has been updated by the previous patch.
Consequently, the arm-cpu-runtime-detection patch modifying this file
should also be adjusted accordingly.

Depends on D207806
