h/q/d: Add utility function for 8x16 and read RGB scalar capability

 - Add utility function for 8x16
 - Add internal function to identify if RGB doesn't
   support scaling that is read from capabilities node.
 - If UI layer needs scaling and RGB pipe doesn't
   support scalar, request a VG pipe
 - On 8x16, request DMA pipe for WFD
