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.

The patch adds a framework to control coreboot and Intel SoC features
dynamically. BIOS reads control information from OEM Section in the
Descriptor Region and control the developer selected features.
With the feature, debug team can control the selected SoC and coreboot
features without rebuilding coreboot.
In order to enable the feature, SOC_INTEL_COMMON_BLOCK_DEBUG_FEATURE has
to be selcted from mainboard.
The OEM section starts from offset:0xf00 till end of the Descriptor
Region(0xfff).

src/northbridge/amd/pi/00660F01/Kconfig does not exist. Remove the
source statement.
Also, no kconfig files under src/soc/intel/common/basecode/. Clean
that up.
