    mpc85xx: Fix HiveAP-330 nvmem mac loader
    
    We actually need to enclose the whole section of partitions in a
    `partitions { ... }` to assign it a `compatible = "fixed-partitions";
    otherwise the partition referred to by `hwinfo` won't be registered
    when bringing up MTD partitions, for example as per:
    
    - <https://forum.openwrt.org/t/tp-link-c2600-missing-default-mac-mtd-partition-in-snapshot/103945/6>
    
    - commit e2b03c16eb44 ("ipq806x: add missing enclosing partitions block for TP-Link C2600")'
    
    Fixes: 8ec21d6bb210 ("mpc85xx: convert mtd-mac-address to nvmem implementation")
