[tegra ALSA] Support built-in speaker
Added support for built-in speaker. Although audio subsystem on
different boards have various topology, Tegra boards usually have
amplifier connected to codec. The patch added a control interface to
expose speaker control widget to user space. Amplifier could be driven
automatically if internal speaker turned on.
