ASoC: dapm: Add a helper to get the CODEC for DAPM kcontrol
We use the same 3 lines to get the CODEC for a kcontrol in a quite a few places. This patch puts them into a common helper function. Having this encapsulated in a helper function will also make it more easier to eventually change the data layout of the kcontrol's private data.
