From: Dave Stevenson <dave.stevenson@xxxxxxxxxxxxxxx>
vc4_dsi was registering both dsi0 and dsi1 as VC4_ENCODER_TYPE_DSI1
which seemed to work OK for a single DSI display, but fails
if there are two DSI displays connected.
Update to register the correct type.
Fixes: 4078f5757144 ("drm/vc4: Add DSI driver")
