arm64: neon: replace generic definition of may_use_simd() 



In preparation of modifying the logic that decides whether kernel mode
NEON is allowable, which is required for SVE support, introduce an
implementation of may_use_simd() that reflects the current reality, i.e.,
that SIMD is allowed in any context.
