soc/intel/common: Add support to control coreboot and Intel SoC features
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).
