Building without CONFIG_ARM64_VHE leads to a linker error due to the SVE
functions being referenced in this list. This is caused by
CONFIG_ARM64_VHE disabling CONFIG_ARM64_SVE and, in turn, preventing the
generation of those symbols. There aren't any references from code, just
this file.

It can be resolved by having the SVE symbol aliases depend on
CONFIG_ARM64_SVE.
