ARCv2: smp: [plat-*]: No need to explicitly call mcip_init_smp()
MCIP now registers it's own per cpu setup routine (for IPI IRQ request) using smp_ops.init_irq_cpu(). So no need for platforms to do that. This now completely decouples platforms from MCIP. Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
