Optimize H573RI/H503KB/H503RB clock config. #2507

Closed dojyorin closed 2 months ago

dojyorin commented 2 months ago

Basically same as "Optimize PLL ratio" in #2506.

Summary

This PR fixes/implements the following bugs/features

By setting SRC / M = 2 N = 250 for PLL1/2/3 you can flexibly determine clock source frequency and easily calculate division P/Q/R.
