sepolicy: Cleanup and cosmetic changes

cherry-picked from upstream device/linaro/dragonboard project.

No functional changes. Renamed few labels and
removed older kernel support.

Earlier I named few framework sysfs labels
based on the execs accessing those sysfs
entries.

For example:
/sys/class/remoteproc u:object_r:sysfs_tqftpserv:s0
just because tqftpserv was the only binary
which needed access of remoteproc sysfs.

That was short sighted and I try to fix some
of such cosmetic mistakes in this patch.

All the remoteproc sysfs entries (adsp/cdsp)
are labeled as sysfs_remoteproc.

Also removed few sysfs entries needed to
bring display on obsolete v5.3 and older
kernels.
