[ Upstream commit bde8b3887add8368ecf0ca71117baf2fd56a6fc9 ]

This patch adds the change required to create the TLV data
for dapm widget kcontrols from topology. This also fixes the following
TLV read error shown in amixer while showing the card control contents.
"amixer: Control hw:1 element TLV read error: No such device or address"
