[PATCH v2 2/2] ARM: da850/omap-l138: Add EVM specific code for VPIF to work

[Prabhakar Lad]

From: Manjunath Hadli <manjunath.hadli@xxxxxx>

Include the expander settings to select VPIF peripheral on
UI card and add registration call in EVM init. Also add platform
data to configure display and capture devices.
