drm/msm/dpu: fix dp audio condition
[ Upstream commit 1e0505a5a7a2fea243f8e6d7e13fcde65f9e41bc ]
DP audio enablement code which is comparing intf_type,
DRM_MODE_ENCODER_TMDS (= 2) with DRM_MODE_CONNECTOR_DisplayPort (= 10).
Which would never succeed. Fix it to check for DRM_MODE_ENCODER_TMDS.
Fixes: d13e36d7d222 ("drm/msm/dp: add audio support for Display Port on MSM")
