nb/intel/ironlake: Clean up DMIBAR/EPBAR registers 

Several registers have been copy-pasted from i945 and do not exist on
Ironlake. Moreover, other register definitions were missing. Use the
newly-added definitions in existing code, in place of numerical offsets.

Tested with BUILD_TIMELESS=1, Packard Bell MS2290 remains identical.
