These patches need to modify binding document and need long term
discuss. I have an idea not to modify binding document so you could be
quicker to merge these patches. The idea is:

1. Keep the patch 'drm/mediatek: fix possible_crtcs', let DPI encoder
support both crtc0 and crtc1.
2. For encoder and crtc, it could find each other by encoder->crtc and
crtc->encoder_mask to configure hardware correctly.
