Patch 1,2,3,4,5 require generic node name for dma and 6/6 is actual
conversion change.

Looking forward towards review comments. Thanks!

---
v3:
- Add Krzysztof's R-b tags for dts changes
- Add qcom,ee as required property(Krzysztof)
- Use type as boolean
- Add min/max to qcom,ee
- Clocks are required ones, skip them as it's users are not fixed.
---
v2:
- Add more variants of ip4019-ap/dk-{01/04/07} for dma node rename
- Add #dma-cells in binding file
- use additionalproperties as false
---

v3:
- Address Krzysztof Comments
- qcom,ee as required property
- Use boolean type instead of flag
- Add min/max to qcom,ee
- skip clocks, as it's users are not fixed
---
v2:
- Use dma-cells
- Set additionalProperties to false

Your change is currently not accepted/merged and don't think it's in
maintainer's queue as well. So, probably it's not in-flight patch as of
now.

Sincere apologies, I saw your original patch only and missed Ack.
Please note, mine change is reviewed by FDT maintainer.

If we are going to have mine binding version, then skipping dts change
here will trigger Rob's bot warning.

This is the 11th most warned on (168 warnings) for missing a schema, so 
I've implemented my only comment and applied. It seems neither this one 
or the other attempt at converting are getting respun.

I didn't respin because Bhupesh mentioned he will send his v5 and then I
couldn't followup.

I realized I should have anyway respin my patch.
