powerpc/64s: Move CPU -mtune options into Kconfig
Currently the -mtune options are set in the Makefile, depending on what
the compiler supports.
One downside of doing it that way is that the chosen -mtune option is
not recorded in the .config.
Another downside is that if there's ever a need to do more complicated
logic to calculate the correct option, that gets messy in the Makefile.
So move the determination of which -mtune option to use into Kconfig
logic.
