This extends the PL011 UART driver with generic DMA engine support
using the PrimeCell DMA engine interface.

Changes since last version:
- Fixed some bugs appearing under huge load, spinlock issues etc
- Adapted to the new generic DMA engine interface

This extends the PL022 UART driver with generic DMA engine support
using the PrimeCell DMA engine interface. Also fix up the test
code for the U300 platform.

This will configure the platform data for the PL180, PL011 and
PL022 PrimeCells found in the U300 to use DMA with the generic
PrimeCell DMA engine.

This patch extends the DMA engine with a PrimeCell superset with
three functions: configure DMA channel, stop channel, and one for
getting the number of bytes pending on a channel. These have been
identified as the basic extensions needed to drive DMA on top of
the PL011, PL022 and PL180 PrimeCells
This is a fourth iteration of the PrimeCell DMA API on top of the
generic DMA devices (sibling to the DMA engine). It's based on
the suggestion from Russell to try and define a specific extension
subset for DMA devices.
Since last iteration the changes are:
- Some necessary extensions to the DMA
