drm/amd/display: Handle seamless boot stream
A seamless boot stream has hardware resources assigned to it, and adding
a new stream means rebuilding the current assignment. It is desirable to
avoid this situation since it may cause light-up issues on the VGA
monitor on USB-C. This commit swaps the seamless boot stream to pipe 0
(if necessary) to ensure that the pipe context matches.
