We currently use a single VC for sending commands and pixel data. The
LP/HS mode for pixel data is correctly set to HS by accident, as we have
set the VC to HS already earlier.

However, if we use a different VC for video data, the VC is in LP mode.
Fix this by always enabling HS mode before starting a frame update.
