smp, hexagon: 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 intterupt is needed for architecture specific code to support generic SMP function call interfaces, so kill the redundant single function call interrupt.
