Subject: AOD - Scale large clock for burn-in protection

Scale the AOD large clock between [0.8, 1.0] in both x,y directions,
in order to keep the clock centered. The large clock will still be
shifted on the y-axis as well.

Bug: 13129102
Test: manual, burn in tests
Change-Id: I86235d39b199a1a10cfb40e474f1e1e58b9c11d8
