[DistroKit] [PATCH] platform-v7a: kernel: re-activate virtio support

[DistroKit] [PATCH] platform-v7a: kernel: re-activate virtio support

[Roland Hieber]

This got lost in commit 5dc9701fe9ec ("platform-v7a: kernel version bump
4.15 -> 4.16"), and resulted in a qemu system no longer able to mount
external 9p devices:

    $ ./configs/platform-v7a/run 9p
    [...]
    [    1.799073] 9pnet_virtio: no channels available for device /dev/root
    [    1.800620] VFS: Cannot open root device "root" or unknown-block(0,0): error -2
    [    1.802147] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

Fixes: 5dc9701fe9ec ("platform-v7a: kernel version bump 4.15 -> 4.16")
