V5 Changes:
* Rebase to arm-soc for-next (per Olof)
* Restructure the DTS/DTSI into board and SoC configurations (per Olof)
* Add model property at the top level (per Olof)
* Move pcie0 under smb and change smb's ranges property to empty since pcie
is not in the same range. (per Olof)
* Change v2m0's ranges property (per Arnd)
* Change timer interrupt type to level-trigger (per Marc)
