This patch adds definition of macro XPAR_XAXIS_SWITCH_NUM_INSTANCES, controls config table parameters with macro XPAR_XAXIS_SWITCH_NUM_INSTANCES. These changes are to avoid compilation errors in Subsystem driver if Subsystem HIP is not included axis_switch as subcore, results axis_switch driver not in BSP.
