pinctrl: cy8c95x0: Respect IRQ trigger settings from firmware

[ Upstream commit 1ddee69108d305bbc059cbf31c0b47626796be77 ]

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)
  CPU: 0 UID: 0 PID: 125 Comm: irq/33-i2c-INT3 Not tainted 6.12.0-00236-g8b874ed11dae #64
  Hardware name: Intel Corp. QUARK/Galileo, BIOS 0x01000900 01/01/2014
  ...
  handlers:
  [<86e86bea>] irq_default_primary_handler threaded [<d153e44a>] cy8c95x0_irq_handler [pinctrl_cy8c95x0]
  Disabling IRQ #33
