Synchronise device tree with linux v5.19-rc5.

For what it's worth to others who may have been impacted, this patch broke my nano booting because the imx8mn.dtsi now has the UART's as subnodes to spba1 which wasn't being included in SPL's device tree. It's likely to impact others who are booting with DM_SERIAL enabled on their Nano.
Sorry about that.
To fix, I had to add a small line of code to my imx8mn-beacon-kit-u-boot.dtsi file with the following:
&spba1 { u-boot,dm-spl; };
With that, my board boots again. If anyone else is using DM_SERIAL and having issues no longer starting, give that a try.
Since there are few nano boards with common -u-boot.dtsi entries, it seems like it makes sense to have a common imx8mn-u-boot.dtsi file like we do for Mini and Plus. I'll try to work on that as I have time. (hopefully today)
Thanks for your help in correcting this.
Cheers
Marcel
