i2s: add support apll clock
using apll_param to setup APLL new apll calculation method, much faster validate freq calculation Ensure that the i2s frequency is greater than the hardware limit Add description of how to calculate apll clock, support apll for other 16-bits audio, check rev0 chip correct space
