[PATCH v3] ARM: S3C24XX: Add WIZnet W5300E01-ARM board support

[Taehun Kim <kth3321@gmail.com>]

- The gpio routines are changed to use the gpio_request() functions from
  comments of Vasily and Sylwester.
- The mistake of adding a character by my email client automatically is fixed.

Please review this patch and apply it if do not have any problems.
