DPS [1] assigns GPT partition type UUIDs to operating system partitions. Root partitions use architecture-specific type UUIDs so the OS can discover the intended root filesystem without relying on a root= cmdline option. Define DPS_ROOT_PARTITION_TYPE_UUID in asm/dps_root.h for parisc and select ARCH_HAS_DPS_ROOT_PARTITION_TYPE_UUID.
