dt-bindings: iio: bma255: Allow multiple interrupts
BMA253 has two interrupt pins (INT1 and INT2) that can be configured independently. At the moment the bmc150-accel driver does not make use of them but it might be able to in the future, so it's useful to already specify all available interrupts in the device tree. Set maxItems: 2 for interrupts to allow specifying a second one. This is necessary as preparation to move the bosch,bma254 compatible from bosch,bma180.yaml to bosch,bma255.yaml since bma180 allows two interrupts, but BMA254 is better supported by the bmc150-accel driver.
