ARM: dts: romulus: Enable video engine
Enable the video engine and add it's optional reserved memory region.
Use 32MB for the reserved memory since the video engine could need up to
two 1920x1200@32bpp source buffers.
Source buffers: 2 * 1920 * 1200 * 4 = 18432000 bytes
In addition, the V4L2 subsystem will allocate any number of compression
buffers, each at most 1/8th the size of the source buffer.
