nvme: Populate NVMe firmware version
Looks like NVMe firmware version is added as `firmware_rev`
property in sysfs. Also its not available in `vpd` blob.
Hence add explicit logic to parse sysfs property.

sysvpd: Add UUID property
Recent LPARs contains "ibm,partition-uuid" device tree property.. which
is unique UUID for each LPAR. This is represented by `MU` keyword.
Lets add support to parse this property and populate vpddb.
Ideally we should enhance libvpd to support new keyword. But that will
add depedency on libvpd version. Hence adding this new keyword (MU)
as DeviceSpecific keyword.

In getDevTreePath(), currently we read the devspec in the sysfs path of
the device to retrive the path represented in /proc/device-tree, some
modern device do not construct devspec file, instead relay on of_node
file, which is a symlink to a file in the device-tree.

devicetreecollector: buildSCSI() - add support for SCSI loc-code
fillQuickVPD failing to find the loc-code, doesn't always attribute to
the missing device-tree entry associated with the sysfs device path.
There are also configurations like USB hubs, to which the SCSI devices
gets connected with special device-tree layout. A USB controller, that
supports both USB 3.0 and USB 2.0 devices will create two USB hubs for
communicating with devices. Where one hub controllers devices with
speeds ranging upto 480M (USB 2.0) and another for devices operating
at the 5000M (USB 3.0). The layout might be little complex when the
USB 3.0 devices are internal on board ones and 2.0 is an external
device.
root hub
/ \
USB hub 1 (2.0) USB hub 2 (3.0)
| / \
external internal internal
device device1 device2
the populated device-tree adds both of the internal devices
under the hub1, that hosts the slower external device, with
the layout:
usb@1
|_ hub@1
|_ cdrom@1 (USB 2.0)
|_ usb-scsi@6 (USB 3.0, internal device 1)
|_ usb-scsi@8 (USB 3.0, internal device 2)
this patch add support to find location code for such SCSI devices
connected to USB hubs in a mix and match of external and internal
devices.
