dsp: dsp stops working when suspend [1/1]

Browse Source 
PD#SWPL-220011

Problem:
The pm-support attribute in the dtsi file of kernel 6.12 does not
match the parsing of probe, resulting in the inability to obtain the
correct value and preventing the DSP from entering the predetermined
suspend processing flow.

Solution:
modify the configuration of pm-support in dtsi

Verify:
