[ARM] S3C64XX: Initial arch header files Add the initial header files for the S3C64XX support to satisfy the minimal requirements to build a kernel. Some definitions will therefore be placeholders or empty functions that will ensure that the system can build and have base functionality. These will be filled in at a later date.

[ARM] S3C64XX: DMA support Add support for the DMA blocks in the S3C64XX series of CPUS, which are based on the ARM PL080 PrimeCell system. Unfortunately, these DMA controllers diverge from the PL080 design by adding another DMA controller register and configuration for OneNAND.
