clk: sunxi-ng: nkm: consider alternative parent rates when determining rate
In case the CLK_SET_RATE_PARENT flag is set, consider using a different
parent rate when determining a new rate.
To find the best match for the requested rate, perform the following
steps for each NKM combination:
- calculate the optimal parent rate,
- find the best parent rate that the parent clock actually supports
- use that parent rate to calculate the effective rate.
In case the clk does not support setting the parent rate, use the same
algorithm as before.
