 score/cpu: Silence ARM and AARCH64 GCC 12 false trigger array warning

 The false trigger is covered in:

 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99578

 GCC 11 and 12 has been patched for constant pointer casts above
 4K. This code casts a constant pointer within the first 4K
 page. As a result the patch disables the warning.

 Updates #4662
