ARM: davinci: da8xx: add pdata-quirks for VPIF capture

For da8xx DT platforms, use pdata-quirks to add legacy platform data for
vpif_capture driver.

Passing legacy platform_data is required until the V4L2 framework, and
subdevice drivers (such as the tvp514x) grow a way of selecting input
and output routing  (c.f. V4L2 s_routing API)

    - removed unnecessary #ifdefs
    - split the init function into two separate routines for the lcdk
      and evm boards]
