Stephen Hemminger 2063b5540e hwdb: add support for VMBUS guids (#8677) 
This addresses missing feature on #8677

Devices in Hyper-V/Azure exist on vmbus and are identified by
UUID value. This patch adds a hardware table so that udevadm
can report properties. I chose names are based on the values
reported in Window Device Manager (for consistency).
The table includes several devices that are not used by Linux
but are present and ignored.

For example:

$ udevadm info -q property /sys/bus/vmbus/devices/58f75a6d-d949-4320-99e1-a2a2576d581c
DEVPATH=/devices/LNXSYSTM:00/LNXSYBUS:00/ACPI0004:00/VMBUS:00/58f75a6d-d949-4320-99e1-a2a2576d581c
DRIVER=hid_hyperv
ID_MODEL_FROM_DATABASE=Microsoft Hyper-V Mouse
MODALIAS=vmbus:9eb6a8cf4a5bc04cb98b8ba1a1f3f95a
SUBSYSTEM=vmbus
USEC_INITIALIZED=11076966

Or with updated kernel the driverctl script.

$ driverctl -b vmbus -v list-devices
