    clk: en7523: fix rate divider for slic and spi clocks
    
    [ Upstream commit 58c53d43142f222221e5a76a7016c4d8f3b84b97 ]
    
    Introduce div_offset field in en_clk_desc struct in order to fix rate
    divider estimation in en7523_get_div routine for slic and spi fixed
    rate clocks.
    Moreover, fix base_shift for crypto clock.
