DaVinci: DM646x - platform changes for vpif capture and display drivers

Browse Source 
VPIF display changes (Chaithrika)

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.

VPIF caputure changes (Murali)

1) Modify vpif_subdev_info to add board_info, routing information and
   vpif interface configuration. Remove addr since it is part of
   board_info

2) Add code to setup channel mode and input decoder path for vpif
   capture driver

Also incorporated comments against version v0 of the patch series and
added a spinlock to protect writes to common registers

Tested on DM6467 on channel 0 using TVP514x. Following bootargs used
for drivers:

   vpif_capture.ch0_bufsize=829440 vpif_display.ch2_bufsize=829440
