From: Jeya R <jeyr@xxxxxxxxxxxxxx> Add property to set DSP domain as non-secure. ADSP/MDSP/SDSP are by default secured, where as CDSP can be either be secured/unsecured. non-secured Compute DSP would allow users to load unsigned process and run hexagon instructions, but limiting access to secured hardware within the DSP. Based on this flag device nodes for secured and unsecured are created.
