arm64: atomics: lse: remove stale dependency on JUMP_LABEL
Currently CONFIG_ARM64_USE_LSE_ATOMICS depends upon CONFIG_JUMP_LABEL,
as the inline atomics were indirected with a static branch.
However, since commit:
21fb26bfb01ffe0d ("arm64: alternatives: add alternative_has_feature_*()")
... we use an alternative_branch (which is always available) rather than
a static branch, and hence the dependency is unnecessary.
Remove the stale dependency, along with the stale include. This will
allow the use of LSE atomics in kernels built with CONFIG_JUMP_LABEL=n,
and reduces the risk of circular header dependencies via <asm/lse.h>.
