[PATCH 2/8] usb: Import USB_INTERFACE_INFO() macro from Linux

[Jonas Karlman]

Import the USB_INTERFACE_INFO() macro from Linux to make it less verbose
to describe a class of USB interfaces.

Signed-off-by: Jonas Karlman <jonas at kwiboo.se>

This macro existed in the initial Linux v2.6.12-rc2 git build.
