Ampere/aarch64 bring-up changes

* Refactor the efi-secure-boot feature (in order for it to be
disabled for certain targets)
* Add support for emag8180 compilation target (used as Enea NFV Access host)
* Add emag8180 support in ostree
* Add support for qemuarm64 compilation target (used as Enea NFV Access VNF)

Note:
The aarch64 family does not support the secure-boot feature yet, so the
"efi-secure-boot" has been disabled.
