sungem: Spring cleaning and GRO support
This patch simplifies the logic and locking in sungem significantly:
- LLTX is gone, all private locks are gone, mutex is gone
- We don't poll the PHY while the interface is down
- The above allowed me to get rid of a pile of state flags
using the proper interface state provided by the networking
stack when needed and overall simplify the driver a lot
- Allocate the bulk of RX skbs at init time using GFP_KERNEL
- Fix a bug where the dev->features were set after register_netdev()
- Added GRO while at it
