mt76: move irq handler in mt76x02-lib moudle

Move mt76x02_irq_handler handler in mt76x02_mmio.c in order to be reused in mt76x0 driver. Move mt76x02_rx_poll_complete routine in mt76x02-lib module. Moreover remove pci_core.c and mt76x2/trace.{c,h} since are empty files Signed-off-by: Lorenzo Bianconi <[email protected]> Signed-off-by: Felix Fietkau <[email protected]>
