Input: xpad - add constants for GIP interface numbers

[ Upstream commit f9b2e603c6216824e34dc9a67205d98ccc9a41ca ]

Wired GIP devices present multiple interfaces with the same USB identification
other than the interface number. This adds constants for differentiating two of
them and uses them where appropriate
