drm/omap: fix replication logic

DSS uses "replication logic" to convert color components from smaller
bit widths to bigger bit widths. Without replication logic, the color
component would be shifted and the least significant bits would be left
at 0, whereas with replication logic, the least significat bits will be
filled with the most significant bit.

For some reason omapdrm leaves replication logic always to off, which,
in the most common case, means that showing 16-bit RGB colors on 24-bit
display gives a bit darker colors than expected.
