[OE-core] [PATCH 1/1] initramfs-framework: include install module in recipe for installation

Wed Jul 12 23:01:12 UTC 2017
From: "Ng, Wei Tee" <wei.tee.ng at intel.com>
Utilized the existing init-install-efi.sh script 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 module is being added in the recipe to handle the
installation process using initramfs-framework.
