[PATCH 1/3] bus: ti-sysc: Fix initializing module_pa for modules without sysc register

[Tony Lindgren]

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.
