The FT6x06 driver used for the Shanling Q1's touchscreen has been extended to report more than one touch point. It can also return the gesture detected by the controller, but this doesn't seem to report anything useful on the Q1. Multi-touch is only useful in 3x3 grid mode since the Rockbox button API cannot report more than one touch point. The FiiO M3K uses the same driver so it's been updated to the multi-touch API, but functionality is unchanged. Change-Id: I4de42f44808d6eb902e3da212d8f936b7a5042c7
