Subject: [PATCH v2 1/2] dt-bindings: iio: imu: icm42600: add interrupt
 naming support

From: Jean-Baptiste Maneyrol <jean-baptiste.maneyrol@....com>

Add interrupt-names field for specifying interrupt used. Only INT1
is supported by the driver currently.

Add minItems 1 for interrupts since interrupt is mandatory for the driver.
