arm: common: For single cores do not use smp_call_function_single
Use smp_call_function_single only for SMP systems. For single cores, call the function directly. Use CONFIG_SMP to determine if its a SMP system.

arm: common: Use noinline to prevent inlining of function
Declare function as noinline so that function which changes during run time does not get inlined and instead gets called. Without this, the function contents get inlined while optimization is turned on.
