[0/2] dmaengine: Add Arm DMA-350 driver

Hi Vinod,

As it says on the tin, here's an initial driver for the Arm DMA-350[1].
This has the intentions of growing into a fully-featured driver, but so
far my only development platform has been an Arm FVP (software model)
which doesn't emulate peripheral requests, so this is as far as I've
been able to get with dmatest alone. However, I figure it's enough to
be worth posting for review, at the very least.

Thanks,
Robin.
