Yes, and the reason was stated in the actual file deleted here. Upstream
change made it to where building in VIRTIO_CONSOLE required building in
all of virtio. This was put in as a quick fix to get kernels building
again, which is why there is no MR to change it outside of pending.
That upstream issue was fixed with
9f30eb29c514589e16f2999ea070598583d1f6ec and this can go away.  Merging
this, it does not need review as CONFIG_VIRTIO_CONSOLE=y is the actual
reviewed and accepted CONFIG status, we are simply deleting a pending.
