pinctrl: cy8c95x0: Respect IRQ trigger settings from firmware

Some of the platforms may connect the INT pin via inversion logic
effectively make the triggering to be active-low.
Remove explicit trigger flag to respect the settings from firmware.

Without this change even idling chip produces spurious interrupts
and kernel disables the line in the result:

  irq 33: nobody cared (try booting with the "irqpoll" option)
