[PATCH v2 net-next 2/2] nfc: s3fwrn5: Remove hard coded interrupt trigger type from the i2c module

[Bongsu Jeon]

From: Bongsu Jeon <bongsu.j...@samsung.com>

For the flexible control of interrupt trigger type, remove the hard coded
interrupt trigger type in the i2c module. The trigger type will be loaded
 from a dts.
