ARC: [SMP] cpumask not needed in IPI send path
The current IPI sending callstack needlessly involves cpumask.
arch_send_call_function_single_ipi(cpu) / smp_send_reschedule(cpu)
ipi_send_msg(cpumask_of(cpu)) --> [cpu to cpumask]
plat_smp_ops.ipi_send(callmap)
for_each_cpu(callmap) --> [cpuask to cpu]
do_plat_specific_ipi_PER_CPU
Given that current backends are not capable of 1:N IPIs, lets simplify
the interface for now, by keeping "a" cpu all along.
