Introduce mtk_wed_buf structure to store both virtual and physical addresses allocated in mtk_wed_tx_buffer_alloc() routine. This is a preliminary patch to add WED support for MT7988 SoC since it relies on a different dma descriptor layout not storing page dma addresses. Co-developed-by:

Jisheng Zhang says: ==================== stmmac: convert to devm_stmmac_probe_config_dt Russell pointed out there's a new devm_stmmac_probe_config_dt() helper now when reviewing my starfive gmac error handling patch[1]. After greping the code, this nice helper was introduced by Bartosz in [2], I think it's time to convert all dwmac users to this helper and finally complete the TODO in [2] "but once all users of the old stmmac_pltfr_remove() are converted to the devres helper, it will be renamed back to stmmac_pltfr_remove() and the no_dt function removed."

Add sw fallback of tx checksum calculation for those tx queues that don't support tx checksum offloading. DW xGMAC IP can be synthesized such that it can support tx checksum offloading only for a few initial tx queues. Also as Serge pointed out, for the DW QoS IP, tx coe can be individually configured for each tx queue. So when tx coe is enabled, for any tx queue that doesn't support tx coe with 'coe-unsupported' flag set will have a sw fallback happen in the driver for tx checksum calculation when any packets to be transmitted on these tx queues.
