V4 Changes:
    * Remove unnecessary smb layer and move motherbord to top level
    * Move include dtsi to top level
    * Remove apb_pclk from sata0 and i2c
    * Fix GIC Virtual Maintanance Interrupt from PPI24 (8) to PPI25 (9)
    * Add 40-bit dma-ranges for motherboard (simple-bus)
    * Remove dma0 (pl330) entry for now since it only supports 32-bit DMA.
      It is basically not used at the moment. It would also need SMMU
      to allow dma remapping to 40-bit DMA range.
    * Add phandle spi0 and spi1
    * Hook up gpio0 pin 7 with MMC Card Detection (CD) support.
    * Changes in pcie0 entry:
        - Add 40-bit dma-ranges
        - Remove interrupts property
        - Add interrupt-map/mask property
        - Fix PCI I/O range 
        - Merge PCI 32-bit ranges
        - Merge PCI 64-bit ranges

NOTE: I am not add a new compatible ID for the sata0 as Rob Herring
      suggested since there is no need at the momement, and I am trying
      to avoid introducing ID unnecessarily.
