msm: vidc: Handle FW errors as Fatal

Currently video driver handles all FW errors such as
SYS_ERROR, SESSION_ERROR and timeouts as non-fatal.
This suppresses FW issues and makes it difficult to
root cause. Hence treat FW errors as Fatal based on
dtsi entry.

When FATAL error occurred, print FW messages by default.
