ENGR00158480 IPUv3:Set IDMAC LOCK for SDC display channels
Set IDMAC_LOCK_EN_1 to make SDC display channels to generate
eight AXI bursts upon the assertion of the DMA request.
This change fixes the random garbage lines when showing
NV12 frames decoded by VPU with V4L2 output on
XGA@60 display's overlay framebuffer. V4L2 output uses
MEM_PP_MEM to do 180 degree rotation.
The issue can be reproduced by the following VPU unit test
on MX53 SMD platform:
/unit_tests/mxc_vpu_test.out -D
'-i /1920x1080_H264_AAC5.1ch.2.1ch_track1.h264 -f 2 -w 1024
-h 768 -r 180 -u 1 -t 1'
