Change in coreboot[master]: arch/arm64: Make ARM64 stages select ARCH_ARM64

[Arthur Heymans (Code Review)]

Hello HAOUAS Elyes, Julius Werner, build bot (Jenkins),

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

https://review.coreboot.org/c/coreboot/+/31315

to look at the new patch set (#6).

Change subject: arch/arm64: Make ARM64 stages select ARCH_ARM64
......................................................................

arch/arm64: Make ARM64 stages select ARCH_ARM64

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

The only difference in config.h is on boards with the Nvidia tegra210
SOC that now select ARCH_ARM64, because its ramstage runs in that
mode. The resulting binary is identical however.
