asoc: lpass-cdc: update logic to vote during ssr

Browse Source 
After ADSP is up during SSR, core_hw_vote may fail and audio_hw_vote
may successed in lpass_cdc_runtime_resume which is caused some timing.
When getting slave device_id, as core_hw_vote is 0, it will skip reading
swr registers and return 0 which causes fail to read correct device_id.
Make this change to avoid calling lpass_cdc_runtime_resume when adsp_up
notification doesn't reach lpass_cdc.
