[Resend Patch v4 05/16] smp, m32r: Kill SMP single function call interrupt

Commit 9a46ad6d6df3b54 "smp: make smp_call_function_many() use logic similar to smp_call_function_single()" has unified the way to handle single and multiple cross-CPU function calls. Now only one interrupt is needed for architecture specific code to support generic SMP function call interfaces,
