The camera HAL and Google Camera App
need selinux permission to run workloads on Aurora DSP. This
change adds the selinux rules too allow these clients to
access the GXP device in order to execute workloads on DSP.
Bug: 264321380
Test: Verified that the camera HAL service and GCA app is able to access the GXP device.
