Hikey960 build fails on AOSP master (S)

[Dean Wheatley]

Steps to repro:

$ repo init https://android.googlesource.com/platform/manifest

$ repo sync

$ lunch hikey960_tv-userdebug

Instructions still state to fetch the following package:

device/linaro/hikey/hikey960/device-hikey960.mk:96: warning: https://dl.google.com/dl/android/aosp/hisilicon-hikey960-OPR-3c243263.tgz

That package has not been updated yet to work with AOSP master (S) build restrictions:

$ make

Failure:

Build errors like:
