NUC7i7BNH is not a board name but a product name of KBL NUC, and it is
outdated to support LOGICAL_PARTITION scenario and HYBRID scenario.
NUC7i7DNH is the product name of KBL NUC that ACRN currently supported,
but its official board name is NUC7i7DNB, so change the folder name from
"nuc7i7bnh" to "nuc7i7dnb" under arch/x86/configs/.

To support modification of OVMF NV storage, add an option "w" for
--ovmf to write the changed OVMF NV data section back to the OVMF image
from guest memory before deinit operations. This will enable persistent
EFI variables. Only option "w" is supported, dm will exit if passing
invalid option. It expects OVMF NV storage writeback with option "w"
when power off or reboot the UOS, poweroff, cold and warm reboot in EFI
shell and when dm recieves SIGINT and SIGHUP.

Because we depend on guest OS to switch x2apic mode to enable lapic pass-thru, vlapic is working at the early stage of booting, eg: in virtual boot loader.
After lapic pass-thru enabled, no interrupt should be injected via vlapic any more.

would check the UUID whether it is matched with the one in VM configurations.
Kata container would maintain few UUIDs to let ACRN launch the VM, so
hypervisor need to add these UUIDs in VM configurations for Kata running.
In the hypercall of hcall_get_platform_info(), hypervisor will report the
maximum Kata container number it will support. The patch will add a Kconfig
to indicate the maximum Kata container number that SOS could support.
In current stage, only one Kata container is supported by SOS on SDC scenario
so add one UUID for Kata container in SDC VM configuration. If we want to
support Kata on other scenarios in the future, we could follow the example
of this patch;
