drm/bridge: tc358767: add bus flags
[ Upstream commit 4842379cbe6e851de914a7132f76f4e200b9a98b ]
tc358767 driver does not set DRM bus_flags, even if it does configures
the polarity settings into its registers. This means that the DPI source
can't configure the polarities correctly.
Add sync flags accordingly.
