The MFC nodes with the memory regions reserved for memory allocations
are missing in the Exynos5420 Peach Pit and Exynos5800 Peach Pi DTS.
This causes the s5p-mfc driver probe to fail with the following error:
[ 4.140647] s5p_mfc_alloc_memdevs:1072: Failed to declare coherent memory for MFC device
[ 4.216163] s5p-mfc: probe of 11000000.codec failed with error -12
Add the missing nodes so the driver probes and the {en,de}coder video
nodes are registered correctly:
[ 4.096277] s5p-mfc 11000000.codec: decoder registered as /dev/video4
[ 4.102282] s5p-mfc 11000000.codec: encoder registered as /dev/video5
