As we are using generic numa implementation code, modify the acpi & numa
init functions name to indicate that generic implementation.

Other than the double include of linux/acpi.h below this looks good to me.

Why do we need this ifdef stuff here?
In particular acpi_disabled is defined in that header
in the !CONFIG_ACPI case so seems like we should include it always.
Also given we've just moved arch/arm64/numa.c to become this file,
it has an include of that header a few lines off the top of this diff anyway.
So I think you can just drop the additional include here.
