drm/vc4: dsi: Register dsi0 as the correct vc4 encoder type

Browse Source 
[ Upstream commit 4d9273c978 ]

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.
