linux-initrd: Support more virtio modules in initrd.
Adds mmio and scsi modules for virtio. scsi one is needed for using
virtio-scsi-pci, that can be a common option on aarch64, where only two
options pop up for mounting disks:
- virtio-scsi-pci
- virtio-blk
While virtio-blk should generally be preferred, sometimes virtio-scsi-pci pops
up first on the internet, so people can use it.
virtio-mmio is a necessity on Aarch64 for virtio-blk to work.
* gnu/system/linux-initrd.scm (default-initrd-modules): Add virtio_mmio and
virito_scsi.
