[PATCH 07/13] twl4030_charger: distinguish between USB current and 'AC' current

The twl4030 charger has two current sources, 'USB' and 'AC' (presumably "Accessory Charger" because it isn't Alternating Current). If 'AC' is providing current, we should set the current limit differently to when it isn't (and so USB is used). So split 'cur' into 'usb_cur' and 'ac_cur' and use ac

Some hardware (e.g: Broadcom's SYSTEMPORT) is capable of automatically extracting and inserting a proprietary switch tag (e.g: Broadcom tag) which saves us packet modifications when using DSA. Add the required ethtool changes and netdevice feature bits to support such devices. Signed-off-by: Flori
