Thanks Bjorn for the cleanup.

I validated PAS and Non- PAS ADSP PIL with the cleanup changes on SDM845.

Adding tag for ADSP PIL.

I am making changes for non-PAS ADSP PIL by creating new file.
In case you plan to rename qcom_adsp_pil.c to qcom_q6v5_pas, please 
include that change with this.
Also, let me know the filename which we should keep it for non-PAS ADSP 
PIL driver.

I tried comparing qcom_q6v5_pil.c with non-PAS ADSP pil driver. I don't 
think that we can combine
them as there are good amount of code differences. However, we can take 
a look into it once
I post non-PAS ADSP PIL.
