Update git submodules

* Update docs/submodules/fuel from branch 'master'
  - Merge "[maas] AArch64: Preseed Armband repositories"
  - [maas] AArch64: Preseed Armband repositories
    
    Preseed Armband common repo-comp for Pike, so we get
    the updated kernel & other packages from the start.
    Requires upstream PR [1].
    
    While at it, also handle related PR merged upstream [2] by
    explicitly setting maas.region.subnets name via j2 instead of reclass
    param expansion in name (allows us to drop the remaining chunk of the
    fabric-from-CIDR patch we used to carry).
    
    Note: opnfv_infra_maas_pxe_network_addres can now be dropped from
    pod_config j2 template in Pharos Fuel installer adapter.
