mainboard/volteer: Enable SaGv for volteer2, delbin & voxel
SaGv needs to be enabled for only QS. On ES2, we are seeing system
instability.
BUG=b:159198381
TEST=Tested for boot. Power and performance tests were run with
volteer2 with qs setup. System showed stability.
Tested for boot stability on on delbin.
