--------------------------------

[ Upstream commit f89e4094 ]

Nvidia HDA HW expects infoframe data bytes order same for both
HDMI and DP i.e infoframe data starts from 5th bytes offset. As
dp infoframe structure has 4th byte as valid infoframe data, use
hdmi infoframe structure for nvidia dp infoframe to match HW behvaior.
