ASoC: soc-dapm.h: Convert macros to return a compound literal

The SND_SOC_DAPM_* helpers family are used to build widgets array in a
static way.

Convert them to return a compound literal in order to use them in both
static and dynamic way.
With this conversion, the different SND_SOC_DAPM_* parameters can be
computed by the code and the widget can be built based on this parameter
computation.
  static int create_widget(char *input_name)
  {
          struct snd_soc_dapm_widget widget;
          char name*;
          ...
          name = input_name;
          if (!name)
                  name = "default";

          widget = SND_SOC_DAPM_INPUT(name);
          ...
  }
