net: stmmac: dma channel control register need to be init first
stmmac_init_chan() needs to be called before stmmac_init_rx_chan() and
stmmac_init_tx_chan(). This is because if PBLx8 is to be used,
"DMA_CH(#i)_Control.PBLx8" needs to be set before programming
"DMA_CH(#i)_TX_Control.TxPBL" and "DMA_CH(#i)_RX_Control.RxPBL".
Fixes: 47f2a9ce527a ("net: stmmac: dma channel init prepared for multiple queues")
