Input: goodix - fix variable length array warning
Fix sparse warning: drivers/input/touchscreen/goodix.c:182:26: warning: Variable length array is used. Replace the variable length array with fixed length. Some Goodix devices have maximum 5 touch points, while others have 10 touch points. Using the maximum length (80 bytes) for all devices will lead to wasting 40 bytes on stack when using devices with maximum 5 touch points. However, that is preferable to using kmalloc which will use even more resources.
