i2c: core: Use fwnode_for_each_child_node_scoped()

Replace the manual __free(fwnode_handle) iterator declaration with the
new scoped iterator macro for cleaner, less error-prone code.

This eliminates the need for explicit iterator variable declaration with
the cleanup attribute, making the code more consistent with other scoped
iterator usage patterns in the kernel.
