Convert Qualcomm ETHQOS Ethernet devicetree binding to YAML.

While at it, also update the MAINTAINERS file to point to the yaml
version of the bindings.

[halaney: Remove duplicated snps,dwmac.yaml properties, add MAINTAINERS]

I picked this up from:
https://lore.kernel.org/netdev/20220929060405.2445745-4-bhupesh.sharma@linaro.org/

Changes since then include:
	* Change MAINTAINERS atomically with the filename change
	* Remove duplicated snps,dwmac.yaml properties

As listed on that thread, the issues Bhupesh saw were due to a bug in
dtschema that has since been fixed.

Drio "This binding describes", but say what is the hardware here.

Isn't this new property? Last time I asked to mention the changes to the
binding done during conversion. Explain shortly why you are adding new
properties.

-Qualcomm Ethernet ETHQOS device
-
-This documents dwmmac based ethernet device which supports Gigabit
-ethernet for version v2.3.0 onwards.
-
-This device has following properties:
-
-Required properties:
-
-- compatible: Should be one of:
-		"qcom,qcs404-ethqos"
-		"qcom,sm8150-ethqos"
-
-- reg: Address and length of the register set for the device
-
-- reg-names: Should contain register names "stmmaceth", "rgmii"
-
-- clocks: Should contain phandle to clocks
-
-- clock-names: Should contain clock names "stmmaceth", "pclk",
-		"ptp_ref", "rgmii"
-
-- interrupts: Should contain phandle to interrupts
-
-- interrupt-names: Should contain interrupt names "macirq", "eth_lpi"
-
-Rest of the properties are defined in stmmac.txt file in same directory
-
-
-Example:
-
