Which part is hard to understand exactly? Perhaps this is clearer?

"Clocks configuration is changed so the I2S controller is now the bit
clock and the frame clock master.  The EPLL output clock is now the 
audio root clock adjusted to each audio sample rate."

Previously the CODEC's internal PLL was used for generating the I2S
bit and frame clocks accorrding to each audio sample rate.
