From: hrdl <git@xxxxxxx> commit 5dc63e56a9cf8df0b59c234a505a1653f1bdf885 upstream. Prior to this patch, the sensing configuration data was not parsed correctly, breaking detection of max_tch. The vendor driver includes this field. This change informs the driver about the correct maximum number of simultaneous touch inputs. Tested on a Pine64 PineNote with a modified touch screen controller firmware.
