pinctrl: cy8c95x0: Don't miss reading the last bank registers

Browse source 
When code had been changed to use for_each_set_clump8(), it mistakenly
switched from chip->nport to chip->tpin since the cy8c9540 and cy8c9560
have a 4-pin gap. This, in particular, led to the missed read of
the last bank interrupt status register and hence missing interrupts
on those pins. Restore the upper limit in for_each_set_clump8() to take
into consideration that gap.

Fixes: 83e29a7a1f ("pinctrl: cy8c95x0; Switch to use for_each_set_clump8()")
