soc/intel/common: Fix buggy code tries to access DESC region
The patch fixes the buggy code which tries to access the Descriptor
Region. The existing code doesn't use correct APIs to access the
Descriptor Region. Hence, error message is getting displayed during
the boot.
BUG=b:229003612
TEST=Build and verify no errors seen while accessing the Descriptor
Region.
