[PATCH] mv643xx_eth: Clean up platform_data configuration
We shouldn't expose the hardware register contents in platform_data. The only things we allow the user to configure are autoneg, speed, and duplex. Add specific platform_data fields for these values and remove the registers configs. Signed-off-by: Dale Farnsworth <dale@farnsworth.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
