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
