History
Jeff LaBundy 4a76d861d9 Input: iqs5xx - simplify axis setup logic 
The present implementation manipulates axis swap and inversion fields
in the device to more or less duplicate what touchscreen_report_pos()
does. The resulting logic is convoluted and difficult to follow.

Instead report the maximum X and Y coordinates in earnest as they are
read from the device, then let touchscreen_parse_properties() fix the
axes up as necessary. Finally, use touchscreen_report_pos() to report
the transformed coordinates.

Last but not least, the maximum X and Y coordinates are not functions
of the number of rows/columns that comprise the touch surface. Either
coordinate is simply limited to 1 below what is reported for absolute
X or Y coordinates when no fingers are present (0xFFFF).
