As skl is fully dependent on dmc to go to low power state (dc5/dc6) which requires a trigger from rpm and to ensure the dmc firmware is available for runtime pm support rpm-reference-count is used by not releasing the rpm reference acquire when starting the firmware loader work.
So moved the intel_csr_ucode_init call after runtime pm enable.
