Platform specific display device setup for DM646x EVM

Add platform device and resource structures. Also define a platform specific
clock setup function that can be accessed by the driver to configure the clock
and CPLD.

Applies to Davinci GIT tree. Minor updates like change in structure name-
subdev_info to vpif_subdev_info and correction to VDD3P3V_VID_MASK value.
