Not sure whether the HEVC encoding profile is exported earlier than the
low-level implementation?
If the subsequent patches are not applied, maybe user-space app queries
the entrypoint for HEVC encoding and then try to use it. In such case it
doesn't work at all.
How about exporting the HEVC encoding profile/entrypoint after the
low-level implementations are already added?
