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.
