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.
