UBUNTU: kvm: [config] Enable ACPI NVDIMM

BugLink: https://bugs.launchpad.net/ubuntu/+source/linux-kvm/+bug/1761854

Enable ACPI NVDIMM Firmware Interface Table to allow kata containers mount
the rootfs from persistent memory (pmemX)

Next configs are needed:
* CONFIG_ACPI_NFIT
* CONFIG_BLK_DEV_PMEM
* CONFIG_LIBNVDIMM

Could this option be =m instead to keep it in sync with xenial/linux config?

Also =m here.

The above two options are also =m on the master kernel.

Apart from that I don't have any objection in enabling these config options.
