Subject: [PATCH 1/3] sysvpd: Add UUID property
Upstream: accepted - expected v1.7.12
Git-commit: fa1638452b8299f1a7f8e9a94259b25218a92acc
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.
