        1. update rx_tail_addr as Jose's comment                                
        2. changes clk_csr condition as Alex's proposition                      
        3. remove init lines in dwmac-mediatek, get clk_csr from dts instead.

This series fix some bugs in stmmac driver                                      
3 patches are for common stmmac or dwmac4:                                      
        1. update rx tail pointer to fix rx dma hang issue.                     
        2. change condition for mdc clock to fix csr_clk can't be zero issue.   
        3. write the modified value back to MTL_OPERATION_MODE.                 
1 patch is for dwmac-mediatek:                                                  
        modify csr_clk value to fix mdio read/write fail issue for dwmac-mediatek
