commit 5081046c0561712badd8cd54e0a0972a855aa300

    microcode: Unify rules to add microcode to CBFS once again
    
    Now that cbfstool supports file alignment, we can use the conveniently
    available <filename>-align handler, and remove the need to have a
    separate rule in src/Makefile.inc just for adding the microcode.
    
    We can also get rid of the layering violation of having the
    CONFIG_PLATFORM_USES_FSP1_0 symbol in a generic src/cpu/ makefile.
    Note that we still have a layering violation by the use of the
    CONFIG_CPU_MICROCODE_CBFS_LOC symbol, but this one is acceptable
    for the time being.
