at86rf230: init xtal_trim with zero
This patch initialize xtal_trim value to zero. The xtal_trim property is an optional device tree value. Currently if no xtal_trim property is given the xtal_trim value can be contain random data, because it's a stack variable. This patch init the xtal_trim value to zero which is also the default value after reset for at86rf230 transceivers.
