Add normal world mhu0_hes0 and mhu0_es0h nodes In Corstone-1000 IoT Reference Design Platform, communication between the host (Cortex-A35) running in normal world (EL0 and EL1) and the external system (Cortex-M3) is done with MHU0.
MHU0 is a bidirectional communication channel described in the device tree through mhu0_hes0 and mhu0_es0h.
