Hi guys

In PR kata-containers/packaging#1006, I've backported Anshuman Khandual's patch series of Enabling memory hot remove on aarch64(https://patchwork.kernel.org/cover/11419305/) to v5.4.x.
This patch series has already been merged, and queued for 5.7.
And after backporting this series, we could finally enable nvdimm/dax on arm64.

See kernel dump info:

[    0.154853] EXT4-fs (pmem0p1): DAX enabled. Warning: EXPERIMENTAL, use at your own risk
[    0.155487] EXT4-fs (pmem0p1): mounted filesystem with ordered data mode. Opts: dax,data=ordered,errors=remount-ro
[    0.155714] VFS: Mounted root (ext4 filesystem) readonly on device 259:1

NVDIMM/DAX is truly working here~~

After backporting patch series of enabling memory hot remove on aarch64
to v5.4.x, we finally could enable nvdimm/dax on aarch64.

Fixes: kata-containers#2601
