ASoC: SOF: Add a tuples array to struct snd_sof_widget

Add 2 new fields to snd_sof_widget to store an array of tuples
defined by struct snd_sof_tuple and the number of tuples. When the
topology gets parsed, the tuples associated with a widget will be stored
in this array and will be used to construct the IPC structure
depending on the IPC version.
