I don't know what the outcome was for the first version, but just
for the record, I would prefer merging the board file into armada-370-xp.c
without renaming that file. Keeping the separate Kconfig entry makes sense
because we want to select different options there. If you have differences
between the implementations (so far the 370/xp code should just work
on 375), you can use a combination of if(IS_ENABLED(CONFIG_*)) and
if(machine_is_compatible()) to do the detection but keep a common
dt_compat list.
