arm64: Remove system_uses_lse_atomics()
There are two variants of system_uses_lse_atomics(), depending on
CONFIG_ARM64_LSE_ATOMICS. The function isn't called anywhere when
CONFIG_ARM64_LSE_ATOMICS is disabled. It can be directly replaced
by alternative_has_cap_likely(ARM64_HAS_LSE_ATOMICS) when the kernel
option is enabled.
No need to keep system_uses_lse_atomics() and just remove it.
