VIGS: Support DP memory and planar pixel formats

VIGS: Support DP memory and planar pixel formats

DP memory is used by some of the tizen
gstreamer plugins, TBM and X.Org video driver.
Its main purpose is to share GEM buffers between
media decoding and presentation layers

Planar pixel formats such as NV21 need to be
supported in order to be able to play video right
from decoder's output buffer, i.e. without
converting it to RGB
