"#address-cells" and "#size-cells" is required only when the I2C
controller has subnodes. Of the four examples given in this document, only
the third has a child node "eeprom@64".
Ohterwise, false positives similar to the following are reported:
/root/linux-next/arch/arm64/boot/dts/hisilicon/hi6220-hikey.dt.yaml: \
i2c@f7100000: '#address-cells' is a required property
/root/linux-next/arch/arm64/boot/dts/hisilicon/hi6220-hikey.dt.yaml: \
i2c@f7100000: '#size-cells' is a required property
In fact, the predecessor of this document: i2c-designware.txt, does not
list "#address-cells" and "#size-cells" as "Required properties" also.
