drm/i915/gen9: csr_init after runtime pm enable
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.

[imre: moved the call right after power domain init to avoid race with
the console modesetting]
