Convert the ATH10K bindings to YAML.

Dropped properties that are absent at the current state of mainline:
- qcom,msi_addr
- qcom,msi_base

qcom,coexist-support and qcom,coexist-gpio-pin do very little and should
be reconsidered on the driver side, especially the latter one.

Somewhat based on the ath11k bindings.

v3 -> v4:
- Disallow interrupt-names for the SNoC variant (unused)
- Remove unnecessary interrupt-names/minItems under qcom,ipq4019-wifi
- Update the MAINTAINERS entry with the shiny new YAML file
- Drop the dts patch, Bjorn picked it up

v3: https://lore.kernel.org/r/20230406-topic-ath10k_bindings-v3-0-00895afc7764@linaro.org

v2 -> v3:
- Ran dt_binding_check explicitly to uncover an issue with the
  example - I had 2 levels of wifi-firmware{}.. Fixed that..

I hope you folks don't mind me resending so quickly, but it was a
trivial issue. Patch 2 unchanged.

v2: https://lore.kernel.org/r/20230406-topic-ath10k_bindings-v2-0-557f884a65d1@linaro.org

v1 -> v2:

Dropped:
- '|' in /description
- /properties/resets/minItems
- Unnecessary level of 'items:' in /properties/ext-fem-name
- reserved-memory in examples
- status in examples
- labels in examples

Added:
- /properties/wifi-firmware/additionalProperties: false
- /properties/wifi-firmware/properties/iommus
- /properties/qcom,coexist-support/enum (and reworded the description)
- wifi-firmware and supplies in the SNoC example

Patch 2 is unchanged, picked up rb.

v1: https://lore.kernel.org/r/20230406-topic-ath10k_bindings-v1-0-1ef181c50236@linaro.org

This is my attempt at (finally) moving ATH10K to YAML.
One inexistent dt property came out as part of that.

Very good, thanks. Clearly I had missed that those were unused during
the review.

I'm curious, what do you mean very little? We set ath10k firmware
parameters based on these coex properties. How would you propose to
handle these?

Is there a reason why you write ath10k in upper case? There are two case
of that in the yaml file. We usually write it in lower case, can I
change to that?

Right, I first thought they did nothing and then realized they're
sent to the fw.. I never amended the commit message though..

No particular reason, my brain just implicitly decided that it
should be this way.. Please unify it (or LMK if you want me to
perform another resend)!

Ok, I can remove that sentence before I commit the patch.

No need to resend. I already changed these to lower case in my pending
branch:

https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git/commit/?h=pending&id=ca448a93d8669a3af5aa644725444aa61b4ca255

I'll remove the coex sentence later.
