Add support for ZII VF610 Dev based designs such as:

    - VF610 Dev, revision B
    - VF610 Dev, revision C
    - CFU1, revision A
    - SPU3, revision A
    - SCU4 AIB, revision C

Changes since v1:

	- Removed questionable preprocessor-level checks

	- Converted board.c to use 'struct gpio'/gpio_request_array
          (as opposed to using custom type)
