configs: add new configuration for qemu-system-xtensa
Tested with Qemu 2.0.0. Overlay is from https://github.com/jcmvbkbc/xtensa-toolchain-build/tree/master/overlays Many thanks to Max Filippov <jcmvbkbc@gmail.com> for his extended help and kernel config examples. A small kernel patch is required, because mkimage does not contain support for Xtensa and the uImage target is failing. Redboot is unused so disable it, too.
