This is not something we ever followed in the past, and I don't think it makes sens here.

"""
Alternatively for some subarchitectures, nodes of the same type can be
grouped together, e.g. all I2C controllers one after another even if this
breaks unit address ordering.
"""

This doesn't apply here, so order strictly by address.
