Merge remote-tracking branch 'aosp/master' into HEADlinaro-android-pie-treble

The FULL_TREBLE support was merged in June. The current
pie-dev branch were create in May from Master.

This update will make sure the next minor Android update
will include hikey with full treble support.

This also gives developers using stable Android codebase on
HiKey/HiKey960 will be able to make use of latest changes.
