Add support for SoCs from the mt7621 family. These all have 2 GMAC ports, both of which are attached to the same internal 1000MBit switch. Currently we only support GMAC1 as the sole CPU port. MT7621 is very similar to MT7620 with only a few registers having different offsets. MT7621 is the first SoC to have the new QDMA engine builtin. The older PDMA engine is also present. unfortunatley, to get the best performance we need to run RX on PDMA and TX on QDMA. This SoC is also the first to have TX vlan offloading and TSO6 support. NeilBrown: the driver didn't work when I tested, so I changed it to match known-working code as much as possible. This included converting to the PDMA engine for TX.
