dm: virtio: rename virtio ring structures and feature bits

Browse Source 
Some virtio ring structures and virtio feature bits are using the
same name/definition as those in kernel header files(linux/
virtio_ring.h, linux/virtio_config.h). Kernel header files must
be included to perform ioctls to support vhost. There are
compiling errors due to duplicated definitions. In this patch
the following renamings are done:

VRING_DESC_F_NEXT -> ACRN_VRING_DESC_F_NEXT
VRING_DESC_F_WRITE -> ACRN_VRING_DESC_F_WRITE
VRING_DESC_F_INDIRECT -> ACRN_VRING_DESC_F_INDIRECT

VRING_AVAIL_F_NO_INTERRUPT -> ACRN_VRING_AVAIL_F_NO_INTERRUPT
VRING_USED_F_NO_NOTIFY -> ACRN_VRING_USED_F_NO_NOTIFY

VIRTIO_F_NOTIFY_ON_EMPTY -> ACRN_VIRTIO_F_NOTIFY_ON_EMPTY
VIRTIO_RING_F_INDIRECT_DESC -> ACRN_VIRTIO_RING_F_INDIRECT_DESC
VIRTIO_RING_F_EVENT_IDX -> ACRN_VIRTIO_RING_F_EVENT_IDX
VIRTIO_F_VERSION_1 -> ACRN_VIRTIO_F_VERSION_1

vring_avail -> virtio_vring_avail
vring_used -> virtio_vring_used
vring_size -> virtio_vring_size
