gpio: pca953x: Remove unused PCAL953X_OUT_CONF from pcal6534_recalc_addr()

First of all, PCAL953X_OUT_CONF is not used in the driver.
Second, it's not a per-bank register, it's a single for the
chip and should be handled differently anyway.

To avoid confusion, drop PCAL953X_OUT_CONF from pcal6534_recalc_addr().
