panfrost: Support parameter queries for main planes

Browse source 
In order to return correct offsets, strides and possibly other
parameters. This is relevant for formats like NV12 and P010 where
the second plane, when produced by the V4L2 decoder, uses the
same FD like the first one, but with an offset.

Analogous to 7a7e577d.

Also use the new helper to get the number of planes.
