arm64: dts: freescale: imx93-tqma9352-mba93xxla: add irq for temp sensor

This adds muxing and configuration of the irq output of the temp
sensor on TQMa93xx that is connected to a GPIO line on MBa93xxLA

While at it, add comment for RTC_EVENT for pcf85063 since the IRQ line
of both devices on SoM are routed to CPU GPIO on MBa93xxLA.
