DMA addresses for devices on the soc bus must be constrained to the 36
address bits that the bus provides.  When no IOMMU is present then this
is easy--DMA addresses are just physical addresses and physical
addresses are (by definition) within the address bits of the bus.  When
an IOMMU is present, however, DMA addresses are virtual addresses.
Despite these addresses being virtual, however, they are still
constrained by the 36 address bits of the bus.

Unless dma-ranges is specified, which causes bus_dma_mask to be set, DMA
allocations for devices on the platform_bus will use all 48 address bits
available by the ARM SMMU. Causing addresses to be truncated on the bus.

This patch increases the #size-cells to 2, in order to be able to define
dma-ranges describe the 36 bit DMA capability of the bus, and bumps

While touching all reg properties, addresses are padded to 8 digits.

Changes since v1:
- Update commit message per discussion with Doug
- Updated "ranges"
- Rebased ontop of a few additional patches from the mailing list
