x86/early quirk: use gen6 stolen detection for VLV
We've always been able to use either method on VLV, but it appears more
recent BIOSes only support the gen6 method, so switch over to that.

x86/early quirk: use gen6 stolen detection for VLV
We've always been able to use either method on VLV, but it appears more
recent BIOSes only support the gen6 method, so switch over to that.
Here will have CallTrace after resume form memory, We tried to find the good
point on -fixes, but trace back to a month ago, it still failed. Need we
further bisect and report a bug for it?
Steps:
---------------------------
1. xinit &
2. echo mem > /sys/power/state
3. resume the machine
