kernel_neon_begin_partial() is no longer available, but the
implementation of kernel_neon_begin() should be sufficient to
satisfy kernel_neon_begin_partial() callers.

Because of the changed semantics of may_use_simd() and
kernel_neon_begin() such code really needs to be ported.

In the meantime, this patch restores buildability of kernel-mode
NEON client code.
