Blackfin ethernet driver: on chip ethernet MAC controller driver 



This patch implements the driver necessary use the Analog Devices
Blackfin processor's on-chip ethernet MAC controller.

[try#2]
 - add timeout control
 - kill dma_config_reg bitfields
 - some trivial cleanup

[try#3]
 - add endianess check
 - add DRV_NAME, DRV_VERSION... driver information string
 - add some comments for silicon anomaly and dma API confusion
 - some code trivial cleanup

[try#4]
 - add Blackfin latest GPIO pin mux opertion with Michael Hennerich's
  help and Dan's review
 - rewrite the DMA descriptor list operation in a more readable way
  by Joe's review

[try#5]
 - cleanup some coding style by Joe's review.

[try#6]
 - 1.1 version fix a bug when set up multicast list pointed by Mr. yoshfuji
 - rearrange the desc_list_free function.
