Subject: [PATCH] staging/bcm2835-codec: Implement additional
g_selection calls for decode
v4l_cropcap calls our vidioc_g_pixelaspect function to get the pixel
aspect ratio, but also calls g_selection for V4L2_SEL_TGT_CROP_BOUNDS
and V4L2_SEL_TGT_CROP_DEFAULT. Whilst it allows for vidioc_g_pixelaspect
not to be implemented, it doesn't allow for either of the other two.
Add in support for the additional selection targets.
