clk: clocking-wizard: Program PLL CP/RES and lock parameters on reconfig
When dynamically reconfiguring the PLL multiplier, the charge pump (CP), loop filter resistance (RES), and lock timing parameters must be updated to match the new multiplier value. Without this, the PLL may fail to lock or exhibit jitter at certain multiply factors. Add lookup tables for CP/RES and lock timing values indexed by multiplier range, and program registers for chargepump and lock delay during dynamic reconfiguration.
