Input: cyttsp5 - fix sensing configuration data structure

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.
