ARM: dts: imx6q-ba16: fix RTC interrupt level

RTC interrupt level should be set to "LOW". This was revealed by the
introduction of commit:

  f181987 ("rtc: m41t80: use IRQ flags obtained from fwnode")

which changed the way IRQ type is obtained.

Fixes: 56c2731 ("ARM: dts: imx: Add Advantech BA-16 Qseven module")
