Add a recipe 'rt-loader-bootbase' to build an image with rt-loader for
devices using the Zyxel BootBase/BootExtension chain. They need a plain
bootable image for initramfs (preferably rt-loader with piggy-backed
uImage) and a plain uImage for flashing. The flashable uImage is later
combined with the loader into a signed/checksummed image.
This template recipe can be used directly for GS1920-24HP, making the
initramfs image more flexible due to using uImage instead of plain
image.
