The sequence to inject microcode updates is virtually the same for all Intel CPUs. The same function is used to inject the update in both CBFS and hardcoded cases, and in both of these cases, the microcode resides in the ROM. This should be a safe change across the board. The function which loaded compiled-in microcode is also removed here in order to prevent it from being used in the future. The dummy terminators from microcode need to be removed if this change is to work when generating microcode from several microcode_blob.c files, as is the case for older socketed CPUs. Removal of dummy terminators is done in a subsequent patch.
