[WIP] codec_adapter: cadence: rework of reset & free procedures - #4162

@slawblauciak fyi - potential for TGL13

@lgirdwood yes lets include this patch

@lgirdwood this should be OK.

@paulstelian97 can you please test this patch with imx-stable-v1.8 branch?

@paulstelian97 any update ?
@slawblauciak @mwasko @mrajwa fyi - could be needed for TGL13
@keyonjie for rc3.

@paulstelian97 any update ?

Not quite yet, but from visual inspection I'm thinking on whether this needs some stress testing (I don't know if codec reset will reuse existing memory or not).

Okay, will back port it once merged.

@lgirdwood @paulstelian97 @keyonjie I tested this patch and it doesn't do any harm. So, we can merge it. I have nothing against.

Anyhow, it doesn't fix #4104 or a related IMX issue. Where second cplay run fails. I'm investigating that on my side.

@paulstelian97 I will get back to you and hand over some codec_adapter IMX issues as next 2 weeks I will be in vacation.

@mrajwa do we need another fix for #4104 ?

@lgirdwood, I need to sync with @zrombel on that as the issue is only reproducable on a slim driver at the moment. I have it on my todo list so if the issue is not covered by this one I will submit another patch.

Ok, could be another cause for #4104 but this is freeing the codec correctly so can be merged.
