This patch proposes to enable kcontrols for siggen and effect type
dapm widgets. This will allow triggering the tone generating siggen
component and also modifying the run-time attributes such as frequency,
amplitude etc. Effect type widgets such as the equalizer could
potentially need kcontrols to pass algorithm data from the userspace.
This patch also renames the function dapm_new_pga() to
dapm_new_kcontrol() so that it does not allude that it applies only
to pga widgets.
