dt-bindings: net: qcom,ethqos: Convert bindings to yaml

Convert Qualcomm ETHQOS Ethernet devicetree binding to YAML.
In doing so add a new property for iommus since newer platforms support
using one, and without such make dtbs_check fails on them.

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

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

ethernet: ethernet@7a80000 {
compatible = "qcom,qcs404-ethqos";
