PD#SWPL-233214 Problem: In the secure playback context, the newly allocated TVP_POOL was not granted access permissions for vdec/hevc. Solution: After allocating a new TVP_POOL, the TEE module checks and synchronizes the current vdec/hevc access permissions, add interface with lock depends on CL: 600559 Verify: S905X5 Change-Id: Iffa38ffabbb5b8edcf5f54dc88c18e21495b568b Signed-off-by: lele xiang <lele.xiang@amlogic.com>
