MT8173 MMPLL frequency settings are different from common PLLs.
It needs different post divider settings for some ranges of frequency.
This patch add support for MT8173 MMPLL frequency setting, includes:

1. Add div-rate table for PLLs.
2. Increase the max ost divider setting from 3 (/8) to 4 (/16).
3. Write postdiv and pcw settings at the same time.
