The Tegra268 HDMI/DP HDA codec reports codec ID 0x10de0037, which is
not present in the Tegra HDMI codec driver's device table. Add this
ID so the driver can bind to the Tegra268 codec.
Tegra268 uses the same HDMI/DP codec programming model as Tegra234.
Reuse MODEL_TEGRA234 to enable DP MST, dynamic pin output assignment
and HDMI interrupt trigger control for Tegra268.
