I wonder if you found this entry missing by code review, or if you have
a machine with that UART and so you actually benefit.

Otherwise looks right to me.

I found it from code review. Since this device could be compiled as a 
module, I think it is better to add this entry.

Using arch/arm/boot/dts/aspeed/aspeed-bmc-ibm-rainier.dts in QEMU
I never experienced an issue. Seems due to defconfig having it =y.
(used arch/arm/configs/aspeed_g5_defconfig)
