Skl is fully dependent on dmc for going to low power state (dc5/dc6). This requires a trigger from rpm. To ensure the dmc firmware is available for runtime pm support rpm-reference-count is used by not releasing the rpm reference if firmware loading is not completed. So moved the intel_csr_ucode_init call after runtime pm enable.
