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>.
