[PATCH v2] arm64: defconfig: Enable memory hotplug and hotremove config

[Kefeng Wang]

Let's enable ACPI_HMAT, ACPI_HOTPLUG_MEMORY, MEMORY_HOTPLUG
and MEMORY_HOTREMOVE for more test coverage, also there are
useful for heterogeneous memory scene.

Hi Catalin and Will，is the defconfig patch picked up from you directly，
the changelog shows most of them merged by SoC maintainers, but this
one is some general feature, I don't know who will take it, thanks.

In general we leave the defconfig patches to the SoC team to avoid
conflicts as they have a lot more changes. Cc'ing Arnd if he wants to
pick it up, otherwise it can go through the arm64 tree.

I added it to my list of patches for 6.1. I'll queue it around rc6
unless Arnd takes it before (and of course, if it won't conflict to the
other SoC changes to defconfig).

Thanks for letting me know that. if conflict, I could rebase and repost.

In general, would like to see MEMORY_HOTPLUG/HOTREMOVE be selected
here for better memory hotplug test coverage. But not sure whether
there had been a rationale for not enabling this on defconfig.

Probably we didn't support the first defconfig was added and forgot
about it.

Applied to arm64 (for-next/defconfig), thanks!
