clk: divider: read-only divider can propagate rate change
When a divider clock has CLK_DIVIDER_READ_ONLY set, it means that the
register shall be left un-touched, but it does not mean the clock
should stop rate propagation if CLK_SET_RATE_PARENT is set
This is properly handled in qcom clk-regmap-divider but it was not in
the generic divider
To fix this situation, introduce a new helper function
divider_ro_round_rate, on the same model as divider_round_rate.
