ARM: smp: elide HWCAP_TLS checks or __entry_task updates on SMP+v6
Use the SMP_ON_UP patching framework to elide HWCAP_TLS tests from the
context switch and return to userspace code paths, as SMP systems are
guaranteed to have this h/w capability.
At the same time, omit the update of __entry_task if the system is
detected to be UP at runtime, as in that case, the value is never used.
