[PATCH v3 3/5] arm64: dts: realtek: Add irq mux to RTD129x

["Andreas Färber" <afaerber-l3A5Bk7waGM@public.gmane.org>]

Update UART nodes with interrupts.

Signed-off-by: Andreas Färber <afaerber-l3A5Bk7waGM@public.gmane.org>
---
 v2 -> v3:
 * Added nodes to rtd129x.dtsi instead of rtd1295.dtsi
 * Adopted misc compatible string
 * Renamed node label from irq_mux to misc_irq_mux for clarity
 
 v1 -> v2:
 * Rebased
