    r375326 in Clang exposes an issue with operator precedence in
    sunxi_div_clk_setup:
    
    drivers/clk/sunxi/clk-sunxi.c:1083:30: warning: operator '?:' has lower
    precedence than '|'; '|' will be evaluated first

    It appears that the intention was for ?: to be evaluated first so that
    CLK_IS_CRITICAL could be added to clkflags if the critical boolean was
    set; right now, | is being evaluated first. Add parentheses around the
    ?: block to have it be evaluated first.
