media: imx-jpeg: Account for data_offset when getting image address

Browse source

Applications may set data_offset when it refers to an output queue. So
driver need to account for it when getting the start address of input
image in the plane.

Meanwhile the mxc-jpeg codec requires the address (plane address +
data_offset) to be 16-aligned.
