wifi: mt76: mmio: move mt76_mmio_wed_{init,release}_rx_buf in common code
Move mt76_mmio_wed_init_rx_buf and mt76_mmio_wed_release_rx_buf routines in common code. This is a preliminary patch to introduce WED support for mt7996 Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
