baytrail: Enable Turbo/Burst and set some magic MSRs
As far as I can tell turbo enabling behaves like it did on haswell so use the standard code.
There are also some magic values to set in some magic MSRs related to turbo and package power so they report correctly.
The L2 cache shrink is enabled and a threshold is set that makes both dual and quad core happy.
C1E is disabled to match the reference code.
