net: ethernet: mtk_eth_soc: ppe: prevent ppe update for non-mtk devices
Introduce an additional validation to ensure that the PPE index
is modified exclusively for mtk_eth ingress devices.
This primarily addresses the issue related
to WED operation with multiple PPEs.
Fixes: dee4dd10c79a ("net: ethernet: mtk_eth_soc: ppe: add support for multiple PPEs")
