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.

Running 'make dtbs_check' with the schema in this patch gives the
following warnings. Consider if they are expected or the schema is
incorrect. These may not be new warnings.

Note that it is not yet a requirement to have 0 warnings for dtbs_check.
This will change in the future.

They obviously wouldn't hurt, but they're unused on the driver side:

for (i = 0; i < CE_COUNT; i++) {
		ret = platform_get_irq(ar_snoc->dev, i);

So I will forbid them.

Assuming DTS does not have them.

Tested locally, no warnings, so looks like nobody used them in dt.
