ASoC: tlv320aic32x4: Model PLL in CCF
Model and manage the on-board PLL as a component in the Core Clock Framework. This should allow us to do some more complex clock management and power control. Also, some of the on-board chip clocks can be exposed to the outside, and this change will make those clocks easier to consume by other parts of the kernel.
