Subject: [PATCH 157/219] fix(enc):fix hang issue of ve roi
Changelogs:
A certain timeout cycles might lead hw bug, causing ve to get stuck when
encoding next frame. It need to restart vcmd and ve core while met the following two
conditions:
1. The hw bug is detected when the vcmd JMP interrupt callback;
2. The encoding tasks are timeout;
