Introduce support for mt7663u 802.11ac 2x2:2 chipset to mt7615 driver. Main difference respect to pcie code base is the usb code needs to configure wtbl from non-atomic context Co-developed-by: Sean Wang <sean.wang@mediatek.com> Signed-off-by: Sean Wang <sean.wang@mediatek.com> Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
