mario.six@gdsys.cc fc76b69873 gpio: pca953x: Fix register reading past 8th GPIO ...

A bug in the pca953x driver prevents correct reading of GPIO input
values beyond the 8th GPIO; all values are reported as zero. Setting of
GPIO output values is not affected.

This patch fixes the reading behavior.
