sb1250-mac: Driver model & phylib update
A driver model and phylib update. It includes the following changes: 1. Removal of unused module options. 2. Phylib support and the resulting removal of generic bits for handling the PHY. 3. Proper reserving of device resources and using ioremap()ped handles to access MAC registers rather than platform-specific macros. 4. Handling of the device using the driver model. Signed-off-by: Maciej W. Rozycki <macro@linux-mips.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
