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.
