HiKey960: Properly integrate mali bifrost gralloc for HiKey960

This properly integrates the mali bifrost gralloc implementation
for HiKey960.

This change depends on a pristine libGLES_mali.so which needs an
updated arm vendor package.

However, after this change, the hisi vendor package is no longer
necessary.
