H8: Set H8/300H as the default architecture for H8 family

  Binutils, in particular ld and gas, use H8/300 as the default architecture.
On the other hand, support for H8/300 has been removed from gcc since
July 2020 (AFAIR) and H8/300H is the default there. This situation causes
that about 30 test cases fail in the following way:

I'm a lot less involved in binutils than I have been in the past, but 
this makes sense to me.  As Jan mentions, we dropped old H8/300 support 
in GCC a while back and default to H8/300H.

Jan, do you have write permissions in the binutils repo?

Imo NEW entries should be added for both gas/ and ld/.

No, I don't.

... suggest to omit the last sentence (also from ld/NEWS).

OK then, I will post a new version of the patch in a few hours.
