Change in coreboot[master]: arch/ppc64: Make PPC64 stages select ARCH_PPC64

[Arthur Heymans (Code Review)]

Hello Kyösti Mälkki, ron minnich, HAOUAS Elyes, build bot (Jenkins), Martin Roth,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/31314

to look at the new patch set (#5).

Change subject: arch/ppc64: Make PPC64 stages select ARCH_PPC64
......................................................................

arch/ppc64: Make PPC64 stages select ARCH_PPC64

Also don't define the default as this result in spurious lines in the
.config.

This also cleans up an unused Kconfig file.

In the generated config.h CPU_QEMU_POWER8 is gone as expected and
ARCH_RAMSTAGE_PPC64 moves a few lines, but the value stays the same.
