sm8750: fastrpc_test fails: hap_example function FAILED with adsp DT nodes ported from downstream

[laklimov]

Hi,

after sending adsp fastrpc v3 patches for sm8750 I found time to actually fix and run fastrpc_test.

Unfortunately, one test fails there. The adsp device tree nodes were ported from downstream files without much changes.
The results of running the test case are the same for cdsp which was merged initially.

The same results are for v75. Apart from that adsprpcd works with dynamic loading of dsp libraries with audio_pd.
