Convert greybus/uart.c from IDR to XArray. The abstract data type XArray
is more memory-efficient, parallelisable, and cache friendly. It takes
advantage of RCU to perform lookups without locking. Furthermore, IDR is
deprecated because XArray has a better (cleaner and more consistent) API.

I haven't verified the use of the new API (yet) but I have a few
comments on your patch, below.

Reported-by: kernel test robot <lkp@xxxxxxxxx>
Signed-off-by: Fabio M. De Francesco <fmdefrancesco@xxxxxxxxx>

I'm not sure I'm right about this...  But the actual change you're
making has nothing to do with what the Intel test robot reported.
I personally find the "Reported-by" here a little misleading, but
maybe the "Link" line that gets added will provide explanation.

Anyway, unless someone else contradicts/corrects me, I'd rather
not have the "Reported-by" here (despite wanting to provide much
credit to <lkp@xxxxxxxxx>...).

You are correct, "Reported-by:" does not make sense here.

There should be a Fixes-from: tag for bugs found in review (not style
issues) but when I suggest it then people just say to use the
Reported-by tag.

I think things caught during review aren't normally worthy
of specific mention in the commit message (though maybe in
the non-committed part under "---").  I mean, that's what
review is for.  And in the case of what <lkp@xxxxxxxxx>
does, that's effectively a technical aspect of "review."

So I don't think "Fixes-from" (whatever that means) or
"Reported-by" make sense for this type of update.
