ARM: smp: Remove use of IPI_CALL_FUNC_SINGLE 



Fix for compile issue which introduced in
'commit 741a8ec5bb22 ("ARM64: smp: Prevent cluster LPM
modes when pending IPIs on cluster CPUs")'.
Correct to use IPI_CALL_FUNC instead of deprecated
IPI_CALL_FUNC_SINGLE. And fix for using smp_cross_call
instead of __smp_cross_call to get needed trace.
