Subject: [PATCH 0/6] media: mediatek: vcodec: Fix decoder under flow and plt test fails randomly 

1: Getting decoder under flow error randomly when do stress test with youtube;
2: Video display black when do plt test with one night.

patch 1 can't regard getting lat buffer as fail.
patch 2 ~ 3 using decoder status instead of core work count.
patch 4 ~ 6 using empty lat buffer as the last one to flush decoder.
