nb/intel/sandybridge: Clean up DMIBAR/EPBAR registers
Several registers have been copy-pasted from i945 and do not exist on Sandy Bridge. Moreover, other register definitions were missing. Use the newly-added definitions in existing code, in place of numerical offsets.
Tested with BUILD_TIMELESS=1, Lenovo ThinkPad X230 remains identical.
