wifi: mt76: mt7921: introduce mt7920 PCIe support
mt7920e is a mt7921 series chipset with 802.11ax 2x2:2SS support. The major difference is in firmware side only, at this moment. This patch would add some mandatory changes for new chip id and firmware download control. Signed-off-by: Deren Wu <deren.wu@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
