[PATCH 08/14] drivers/firmware/sdei: Cleanup on cross call functions

[Gavin Shan]

This applies cleanup on the corss call functions, no functional
changes is introduced:

   * Cleanup struct sdei_crosscall_arg to use tab between fields
     and their types.
   * Move sdei_cross_call_return() ahead of sdei_do_cross_call().
   * Refactor CROSSCALL_INIT to use "do { ... } while (0)".
