Fixes the following denial:
type=1400 audit(0.0:4): avc: denied { read } for comm="android.hardwar" name="compatible" dev="sysfs" ino=28205 scontext=u:r:hal_bootctl_default:s0 tcontext=u:object_r:sysfs_dt_firmware_android:s0 tclass=file permissive=0
This permission is needed for ReadDefaultFstab, which searches the device tree for fstab entries. Devices that use dt-fstab may fail to find the misc block device.
Bug: 143589455
Test: manual test
