The sizeimage of each plane are calculated the same way for 8bit and
10bit bitstream. Need to enlarge the sizeimage with simeimage*5/4 for
10bit bitstream when try and set fmt.

   Scale up the sizeimage by 25% for 10-bit bitstreams in try_fmt./

I'd skip the two 10 bit variables (dram_y_10bit & dram_c_10bit) and
instead do it like this:

```
   dram_stride = pix_fmt_mp->width;
   if (ctx->is_10bit_bitstream)
     dram_stride = dram_stride * 5 / 4;

   dram_y = dram_stride * pix_fmt_mp->height;
   dram_c = dram_y / 2;

   if (pix_fmt_mp->num_planes == 1) {
     pix_fmt_mp->plane_fmt[0].bytesperline = dram_stride;
     pix_fmt_mp->plane_fmt[0].sizeimage = dram_y + dram_c;
   } else {
     pix_fmt_mp->plane_fmt[0].bytesperline = dram_stride;
     pix_fmt_mp->plane_fmt[1].bytesperline = dram_stride;
     pix_fmt_mp->plane_fmt[0].sizeimage = dram_y;
     pix_fmt_mp->plane_fmt[1].sizeimage = dram_c;
     ...
   }
```

Also, why do you call all the variables dram?

Please this isn't tested, but shows the general direction to repeat a
lot less code.

Greetings,
Sebastian

Hi,

Can we stop adding more layers of custom code and port to v4l2-common helpers
please.

regards,
Nicolas
