When apply rt patch or turn on hardirq threaded in kernel,
play audio by application with realtime schedule policy hangs the system.
It is caused by:
Requesting SDMA channel, a specific channel is used to load script
and context from memory.
This load phase also uses sdma to transfer, then poll
a complete flag within a while(1) loop.
When application with realtime schedule policy request sdma channel,
it will preempt threaded irqs and prevent complete flag to be set.
So a deadlock appears.

These new scripts support ssi dual fifo.
Pan Qihong-B30266 provide the usage:
-----------
mcu_2_ssiapp and ssiapp_2_mcu are supporting
SSI tx/rx residing on peripheral DMA region.
mcu_2_ssish and ssish_2_mcu are supporting
SSI tx/rx residing on shared peripheral DMA region.
With all these 4 scripts, will support all the 3 SSIs.
