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
