Driver for pxa architectures

Hi Vinod,

This serie introduces a new driver for Marvell pxa architectures. There is a
full rationale explanation in patch 3/5 on why mmp_pdma was not reused nor
patched incrementally.

This new driver provides all the capabilities to port all the drivers of pxa
architecture to dmaengine. It was tested against the most dma advanced user I
know (pxa_camera), as well a more casual ones (pxamci and dmatest).

This is big piece of code, so I expect the review will take time. If we converge
on it, it will be maintained as well as part of the pxa architeture
maintainance.

It is as well one of the last steps (or so I hope) for pxa architure to be part
of the multiplatform ARM architecture, and at the same time keep its legacy
platforms operational. It will kill arch/arm/plat-pxa/dma.c in the long term.

Cheers.
