zynq: add sdcard image support
Implement the generation of sdcard images with ext4 or squashfs + f2fs overlay, but only enable the latter automatically Additionally, add mkf2fs and e2fsprogs to default packages to manipulate ext4 and f2fs filesystems Finally, disable the automatic generation of initramfs and rootfs.tar.gz images, as they are no longer required (they can still be selected in menuconfig) Signed-off-by: Luis Araneda <luaraneda@gmail.com>
