    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.
