Move final Intel chipsets with ME to intel/common/firmware

This switches the final 4 Intel platforms that use ME firmware from
using code specific to the platform to the common IFD Kconfig and
Makefile.

braswell, broadwell, bd82x6x (cougar point & panther point) and ibexpeak

-	  If you don't have an Intel Firmware Descriptor (ifd.bin) for your

-	  Though, the resulting coreboot.rom will not contain all parts required
-	  to get coreboot running on your board. You can however write only the

-	  firmware might be provided in coreboot's 3rdparty/blobs repository. If
