The following are the avc denials that are addressed:

avc: denied { call } for pid=889 comm="system_server"
scontext=u:r:system_server:s0 tcontext=u:r:hal_gnss_default:s0
tclass=binder permissive=0

avc: denied { call } for scontext=u:r:hal_gnss_default:s0
tcontext=u:r:system_server:s0 tclass=binder permissive=0

avc: denied { read } for name="hw" dev="mmcblk0p43" ino=1837
scontext=u:r:hal_gnss_default:s0 tcontext=u:object_r:system_file:s0
tclass=dir permissive=0

avc: denied { open } for path="/system/lib64/hw" dev="mmcblk0p43"
ino=1837 scontext=u:r:hal_gnss_default:s0
tcontext=u:object_r:system_file:s0 tclass=dir permissive=0

Bug:31974439

Test: Checked that there no more related avc denial messages related to
the GNSS HAL in dmesg.
