ath10k: do not enforce interrupt trigger type

ath10k: do not enforce interrupt trigger type

Interrupt line can be configured on different hardware in different way,
even inverted.  Therefore driver should not enforce specific trigger
type - edge rising - but instead rely on Devicetree to configure it.

All Qualcomm DTSI with WCN3990 define the interrupt type as level high,
so the mismatch between DTSI and driver causes rebind issues:

  $ echo 18800000.wifi > /sys/bus/platform/drivers/ath10k_snoc/unbind
  $ echo 18800000.wifi > /sys/bus/platform/drivers/ath10k_snoc/bind
  [   44.763114] irq: type mismatch, failed to map hwirq-446 for interrupt-controller@17a00000!
  [   44.763130] ath10k_snoc 18800000.wifi: error -ENXIO: IRQ index 0 not found
