firmware: arm_sdei: Cleanup on cross call function
This applies cleanup on the cross call functions, no functional
changes are introduced:
* Wrap the code block of CROSSCALL_INIT inside "do { } while (0)"
as linux kernel usually does. Otherwise, scripts/checkpatch.pl
reports warning regarding this.
* Use smp_call_func_t for @fn argument in sdei_do_cross_call()
as the function is called on target CPU(s).
* Remove unnecessary space before @event in sdei_do_cross_call()
