mt76x0: use mt76_register_device for device registration
Use mt76_register_device routine for device registration. mt76_register_device allows to enable VHT support on 5GHz band. Overwrite unsupported vht features with mt76x0_vht_cap_mask routine. Remove macaddr field of mt76x0_dev data structure and use the mt76_dev one. Moreover remove following unused routines: - mt76_init_sband - mt76_init_sband_2g - mt76_init_sband_5g Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
