Sean Anderson	425c08faa8	clk: k210: Try harder to get the best config ... In some cases, the best config cannot be used because the VCO would be out-of-spec. In these cases, we may need to try a worse combination of r/od in order to find the best representable config. This also adds a few test cases to catch this and other (possible) unlikely errors.

Sean Anderson	6e23c9f0c1	test: dm: k210: Reduce duplication in test cases ... Having to copy-paste the same 3 lines makes adding new test cases error-prone. Use a macro.

Sean Anderson	019ef9a3f3	clk: Add K210 pll support ... This pll code is primarily based on the code from the kendryte standalone sdk in lib/drivers/sysctl.c. k210_pll_calc_config is roughly analogous to the algorithm used to set the pll frequency, but it has been completely rewritten to be fixed-point based.
