nb/intel/sandybridge: Drop casts from DEFAULT_{MCHBAR,DMIBAR}
This allows us to drop some casts to uintptr_t around the tree.
The MCHBAR32 macro still needs a cast to preserve reproducibility.
Only the native raminit path needs the cast, the MRC path does not.
Tested with BUILD_TIMELESS=1, these boards remain identical:
- Lenovo ThinkPad X230
- Dell OptiPlex 9010
- Roda RW11 (with MRC raminit)
