[Biao Huang]

This series fix some bugs and add some features in stmmac driver.               
5 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.                 
        4. add support for hash table size 128/256                              
        5. add mdio clause 45 access from mac device for dwmac4.                
1 patche is for dwmac-mediatek:                                                 
        1. modify csr_clk value to fix mdio read/write fail issue for dwmac-mediatek.
