Moved, renamed, and deleted files

The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

-/**
- * virtio_config_ops - operations for configuring a virtio device
- * @get: read the value of a configuration field
- *	vdev: the virtio_device
- *	offset: the offset of the configuration field
- *	buf: the buffer to write the field value into.
- *	len: the length of the buffer
- * @set: write the value of a configuration field
- *	vdev: the virtio_device
- *	offset: the offset of the configuration field
- *	buf: the buffer to read the field value from.
- *	len: the length of the buffer
- * @get_status: read the status byte
- *	vdev: the virtio_device
- *	Returns the status byte
- * @set_status: write the status byte
- *	vdev: the virtio_device
- *	status: the new status byte
- * @request_vqs: request the specified number of virtqueues
- *	vdev: the virtio_device
- *	max_vqs: the max number of virtqueues we want
- *      If supplied, must call before any virtqueues are instantiated.
- *      To modify the max number of virtqueues after request_vqs has been
- *      called, call free_vqs and then request_vqs with a new value.
- * @free_vqs: cleanup resources allocated by request_vqs
- *	vdev: the virtio_device
- *      If supplied, must call after all virtqueues have been deleted.
- * @reset: reset the device
- *	vdev: the virtio device
- *	After this, status and feature negotiation must be done again
- *	Device must not be reset from its vq/config callbacks, or in
- *	parallel with being added/removed.
- * @find_vqs: find virtqueues and instantiate them.
- *	vdev: the virtio_device
- *	nvqs: the number of virtqueues to find
- *	vqs: on success, includes new virtqueues
- *	callbacks: array of callbacks, for each virtqueue
- *	names: array of virtqueue names (mainly for debugging)
- *	Returns 0 on success or error status
- * @del_vqs: free virtqueues found by find_vqs().
- * @get_features: get the array of feature bits for this device.
- *	vdev: the virtio_device
- *	Returns the first 32 feature bits (all we currently need).
- * @finalize_features: confirm what device features we'll be using.
- *	vdev: the virtio_device
- *	This gives the final feature bits for the device: it can change
- *	the dev->feature bits if it wants.
- * @bus_name: return the bus name associated with the device
- *	vdev: the virtio_device
- *      This returns a pointer to the bus name a la pci_name from which
- *      the caller can then copy.
