USB: CDC-ACM quirk for MTK GPS
This patch adds a device quirk for a MediaTek Inc GPS chipset. The device implements USB CDC ACM, but is missing the union descriptor, so the ACM class driver fails to probe the device. I've tested this patch with an iBlue A+ GPS which uses this chipset and using kernel 2.6.28-rc9.
