[ Upstream commit 7bad5af826aba00487fed9a3300d3f43f0cba11b ]
We have interconnect target modules with no known registers using only clocks and resets, but we still want to detect them based on the module IO range. So let's call sysc_parse_and_check_child_range() earlier so we have module_pa properly initialized.
