ASoC: dapm: Add encoder and decoder widget types to kcontrol handling

This patch fixes the issue where encoder or decoder widget
types are assigned kcontrols in a topology but get ignored.
The controls were parsed successfully but were not registered
as ALSA kcontrols.

In dapm_create_or_share_kcontrol() the snd_soc_dapm_encoder
and the snd_soc_dapm_decoder are added to the switch statement
to be handled similarly as e.g. the snd_soc_dapm_effect for
assigning a proper long control name.

In dapm_widget_show_component() the snd_soc_dapm_encoder and
the snd_soc_dapm_decoder are added to switch statement to let
them to be shown in the debugfs power state output.

In snd_soc_dapm_new_widgets() the  snd_soc_dapm_encoder and the
snd_soc_dapm_decoder are added to same switch case handling as
e.g. snd_soc_dapm_effect to be registered with dapm_new_pga().
The previous operation with default in the switch statement
silently ignored them. Note: Despite the function name, the
dapm_new_pga() is generic utility that calls
dapm_create_or_share_kcontrol() for each kcontrol of the widget.
