Subject: [PATCH] nfc: nxp-nci: remove interrupt trigger type

From: Carl Lee <carl.lee@....com>

For NXP NCI devices (e.g. PN7150), the interrupt is level-triggered and
active high, not edge-triggered.

Using IRQF_TRIGGER_RISING in the driver can cause interrupts to fail
to trigger correctly.

Remove IRQF_TRIGGER_RISING and rely on the IRQ trigger type configured
via Device Tree.
