[PATCH 13/50] drm/amd/display: When resync fifo ensure to use correct pipe ctx

From: Alvin Lee <alvin.lee2 at amd.com>
We resync the FIFO after each pipe update in apply_ctx_to_hw.
However, this means that some pipes (in hardware) are based on the
new context and some are based on the current_state (since the pipes
are updated on at a time). In this case we must ensure to use the
pipe_ctx that's currently still configured in hardware when turning
off / on OTG's and reconfiguring ODM during the resync.
