cpu: Add CPU microcode file to cbfs with 16-byte alignment
On x86 there is a 16-byte alignment requirement for the
addresses containing the CPU microcode. The cbfs files
containing the microcode are used in memory-mapped fashion
when loading new mircocode. Therefore, the data payload's
address/offset of a cbfs file in flash dictates the resulting
alignment. Fix this by processing the CPU microcode cbfs
file separately as it uses $(CBFSTOOL) to find the proper
location within the provided rom image.
