Pull MIPS updates from Ralf Baechle:
 "More hardware support across the field including a bunch of device
  drivers.  The highlight however really are further steps towards
  device tree.

  This has been sitting in -next for ages.  All MIPS _defconfigs have
  been tested to boot or where I don't have hardware available, to at
  least build fine."

Compatibility with many Cavium evaluation boards.
- reg: The base address of the the CF chip select banks. Depending on
the device configuration, there may be one or two banks.
- cavium,bus-width: The width of the connection to the CF devices. Valid
values are 8 and 16.
- cavium,true-ide: Optional, if present the CF connection is in True IDE mode.
- cavium,dma-engine-handle: Optional, a phandle for the DMA Engine connected
