By making the install-efi module a part of initramfs-module that is
enabled unconditionally, parted now needs to be built for the target
even when only the rest of initramfs-module is used.

Can the module please be split out into its own recipe?

Alternatively one could add a PACKAGECONFIG for it, but that's less
flexible.

[OE-core] [PATCH 2/3] initramfs-framework: include install-efi module in recipe for installation

[wei . tee . ng]

From: "Ng, Wei Tee" 

Utilized the existing init-install-efi.sh script and renamed it to
install-efi.sh to manage the installation process of images in
initramfs-framework model. This script will be executed when
"install" option is being chosen in the grub menu and install
the image on the target platform. A new install-efi module is
being added in the recipe to handle the installation process
using initramfs-framework.

[YOCTO #10989]

This version solve the failure of the oe-selftest which is related to the 
allarch issues.
