Subject: phosphor-hostfw-image: Create recipe

Create a recipe to add host firmware files to the BMC image files.
Via a bbappend, this recipe provides a mechanism
to have content be added to a flashable BMC image and an image
file to be added to the code update tarball to be updated
during a firmware update.

(From meta-phosphor rev: 39b1ff0dcd12f15dc651aa20cb85cdec903cb5de)
