[PATCH net-next 07/11] net: stmmac: move initialisation of queues_to_use to stmmac_plat_dat_alloc()

["Russell King (Oracle)" <rmk+kernel@armlinux.org.uk>]

Move the default initialisation of plat_dat->tx_queues_to_use and
plat_dat->rx_queues_to_use to 1 to stmmac_plat_dat_alloc(). This means
platform glue only needs to override this if different.
