mpv: make the drmprime overlay framebuffer the whole frame

Browse Source 
The DRM framebuffer was made the size of the source rect while SRC_X and
SRC_Y place that rect inside the frame. With panscan or a crop the rect
reaches past the framebuffer, the atomic commit fails with ENOSPC and the
plane stays dark. The patch, Upstream-Status: Pending, makes the
framebuffer the size of the frame.

Subject: [PATCH] hwdec_drmprime_overlay: make the framebuffer the whole frame
The framebuffer for the DRM plane was made the size of the source rect,
while SRC_X and SRC_Y place that rect inside the frame. As soon as the
rect does not start at the top left, with panscan or a video crop, it
reaches past the framebuffer and the atomic commit fails with ENOSPC; the
plane stays dark. Make the framebuffer the size of the frame and let the
SRC_* properties pick the part that is shown.
