[PATCH v4 10/15] drivers/firmware/sdei: Cleanup on cross call function

[Gavin Shan]

This applies cleanup on the cross call functions, no functional
changes are introduced:

   * Refactor CROSSCALL_INIT to use "do { ... } while (0)" to be
     compatible with scripts/checkpatch.pl
   * Use smp_call_func_t for @fn argument in sdei_do_cross_call()
   * Remove unnecessary space before @event in sdei_do_cross_call()
