r-car m2: set PREFERRED_VERSION_gstreamer1.0-omx* to 1.0.% when h/w acceleration enabled
r-car m2: set PREFERRED_VERSION_gstreamer1.0-omx* to 1.0.% when h/w acceleration enabled

The R-Car M2 multimedia acceleration provides acceleration support for GStreamer 1.2.3
and OMX 1.0, so set the preferred version to 1.0.% when acceleration is enabled. Required
for meta-ivi which supports both Gst 1.2.3/OMX 1.0 and 1.4.x/1.2 but defaults to 1.4.x/1.2.

Thank you to Tadao Tanikawa and his work on this within AGL:
