When using other platform architectures, in the init of the qcom_scm
driver, of_node_put is called on /firmware if no qcom dt is found.
This results in a kernel error: Bad of_node_put() on /firmware.
These calls to of_node_put from the qcom_scm init are unnecessary as
of_find_matching_node and of_platform_populate are calling it
automatically.
Remove the calls to of_node_put() on fw_np.
