MLK-18502-01 plat: imx8mm: fix audio fifo underrun issue

A53 WAIT mode is specific for OS cpuilde.  The MASTER1 & MASTER2
mapping in A53 domain should be clear, otherwise the 'noc2supermix'
and 'supermix2noc' ADB400 async port will be power down when A53
enters WAIT mode.If the ADB400 is power down in WAIT mode, all the bus
request from supermix to  noc wrapper will be blocked.
