[media] ARM: davinci: da850 evm: Add EVM specific code for VPIF to work

Browse Source 
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.

help
Say Y if you want to use Video Port Interface (VPIF) on the
DA850/OMAP-L138 EVM. The Video decoders/encoders are found on the
UI daughter card that is supplied with the EVM.
