[PATCH v4 2/2] ARM: dts: aspeed: Add AMD DaytonaX BMC

Sorry, I still have some questions, can you please help me?

I work with kernel in the context of the OpenBMC project, and it is
not possible to run 'make dtbs_check' in the linux kernel devshell
(Yocto). So I've tried to download upstream kernel and have performed
the following commands to make the dtbs_check:
```
$ make ARCH=arm aspeed_g5_defconfig && make ARCH=arm dtbs_check
```
This gave me a ton of output regarding all the problems in all of the
aspeed boards. 'wc -l' says that the log file is about 7080 lines
long. Is it possible to get the output only for my target DTS? The
article that you've referred to
(https://www.kernel.org/doc/Documentation/devicetree/writing-schema.rst)
only have the information about how to run checks against one schema
(DT_SCHEMA_FILES), but it is not the same thing.

I've manually tried to split the output regarding my DTS file, but
even so the output is overwhelming - https://pastebin.com/b92rnBt0. I
just don't understand if the mentioned things are about the common
"aspeed-g5.dtsi" file that I should ignore or the things regarding
errors in my submitted DTS file. Can you give me some advice on that?

Anyway I think I've updated my patchset regarding all the things that
you've mentioned explicitly. I've split the patchset to two as you've
requested and have added a cover letter. I hope I did everything
correctly.
But I'm still not sure about this 'make dtbs_check'. If I did
something wrong, please correct me.

Best regards,
Konstantin Aladyshev
