Add a callback hook to the chip ops struct to allow chips to have their
specific fifo watermark update function. Currently only cdv actually
tries to set wms based on crtc configuration but if/when the other chips
needs it we can attach a callback for them as well.

This patch aims to unify the bits and pieces that are common (or similar
enough) for pll clock calculations. Nothing makes use of this code yet
That will come in later patches.
