0a5bb69982 board/qemu/ppc64le-powernv8: fixup paths to images in qemu command line
Use full relative pathes for rootfs and kernel, like in other
readme's.

7d914839a4 configs/qemu_ppc64le_powernv8: new defconfig
PowerNV is the platform using the OPAL [1] firmware on OpenPOWER
systems. OPAL first loads a kernel and an initramfs image based on
buildroot including a second boot loader petitboot [2]. The latter
does device discovery and kexecs a new Linux image from disk or
network.

QEMU implements PowerNV machines [3] for the POWER8, POWER9 and
Power10 processors which are used for dev and tests. POWER8 images
being compatible with POWER9 and Power10, simply add a single
qemu_ppc64le_powernv8 board for all.

The QEMU script boots directly from a nvme disk because it is simple
enough but a real system would boot from a ramfs first.
