[PATCH v1 0/7] s390x: Add support for virtio-net-pci boot device

This series enables network booting via virtio-net-pci on s390x.

Refactor virtio-net to separate virtio-ccw specific logic and
create generic virtio-net helpers, and add support for booting
from virtio-net-pci devices with proper endianness handling.
Add support for the loadparm property during network boot.

Add corresponding test coverage to verify correct network boot
functionality with virtio-net-pci devices.
