[PATCH] Reserve device ID 51 for Virtio HAB (Host-Guest Auxiliary Bridge) device

Virtio HAB device is an inter-VM IPC and shared-memory device
intended for multi-VM systems.

Virtio HAB provides named service channels between guest VMs
and primary/service VM, primarily targeting platform-specific
hardware accelerators and system services (deployed in Qualcomm
automotive platforms).

It also supports bi-directional zero-copy shared-memory lifecycle
operations (export/unexport/import/unimport).

The driver is shipping in Qualcomm automotive IVI products,
supports Gunyah, QNX, Green Hills, Red Bend and Xen hypervisors
(KVM in progress), and is being prepared for Linux kernel upstreaming.
