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) Change-Id: I8ca1c35e2c1f1b4f0d83bd7bb080b8667dbe3cb3 Signed-off-by: Angel Pons <th3fanbus@gmail.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/45349 Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
