* [PATCH] kernel-fitimage: add initramfs support

To: openembedded-core; +Cc: marex
If INITRAMFS_IMAGE is set, build an additional fitImage containing the
initramfs. Copy the additional fitImage and the source .its file used to
create it to DEPLOYDIR. The fitImage containing the initramfs must be
built before do_deploy and after do_install to avoid circular dependencies.
UBOOT_RD_LOADADDRESS - Specifies the load address used by u-boot for the
initramfs.
UBOOT_RD_ENTRYPOINT - Specifies the entry point used by u-boot for the
initramfs.

I really don't like the todo here :) Maybe you can check if the DT image
ends with .dtb or not to discern ramdisk and DT ?
