Subject: [PATCH 1/3] xpad.c: Added flags into xpad_device structure and
removed dpad_mapping.
This changes are expected to simplify further improves of this driver,
We will need to add information if the driver is xbox360 device or not.
Second option was to simply add u8 is_360, but what if we'll need to know
if device is a wheel? Or if the device can have keyboard (or headset) attached.
