ARM: mvebu: add missing DT Mbus ranges and relocate PCIe DT nodes for RN102

When f9f47a82 and 64b6f949 were introduced, Netgear ReadyNAS 102 .dts
file was queued for inclusion and missed the update to have Mbus (and
then BootROM) ranges properties declared. It also missed the relocation
of Armada 370/XP PCIe DT nodes introduced by 5592cad2 after 9a7da4e2.
This patch fixes that which makes 3.12-rc3 bootable on the NAS.
