 custom GMAC label

Hi,

for dsa slave-ports there is already a property "label", but not for master/cpu-ports

https://elixir.bootlin.com/linux/v5.12-rc8/source/arch/arm64/boot/dts/mediatek/mt7622-bananapi-bpi-r64.dts#L163

handled here:

@ilya maybe you can rename slave-ports instead of master-port without code change?

i also prefer a more generic way to name interfaces in dts, not only in the mtk-driver, but the udev-approach is a way too, but this needs to be configured on each system manually...a preset by kernel/dts will be nice (at least to distinguish master/cpu- and user-ports).

regards Frank
