exynos5: asv: Call the core ASV code early

Change the priority of ASV code initialization. The core ASV code
finds the speed group, lot id and exposes it to various consumer
drivers like busfreq, G3D and CPUfreq. Among these, the G3D driver
is getting called before the core code and thus is always getting
the ASV speed group as 0. Fix this by calling the core ASV early.

BUG=chrome-os-partner:16796
TEST=Checked that G3D, ARM and INT drivers are all getting the same
ASV group on 2 different boards (1 MP and 1 PVT). Also, verified that
the voltages match that speed group.
