Joey Gouly 7c4cce5700 arm64: lib: Import latest version of Arm Optimized Routines' strncmp
commit 387d828adffcf1eb949f3141079c479793c59aac upstream.

Import the latest version of the Arm Optimized Routines strncmp function based
on the upstream code of string/aarch64/strncmp.S at commit 189dfefe37d5 from:
  https://github.com/ARM-software/optimized-routines

This latest version includes MTE support.

Note that for simplicity Arm have chosen to contribute this code to Linux under
GPLv2 rather than the original MIT OR Apache-2.0 WITH LLVM-exception license.
Arm is the sole copyright holder for this code.
