hwc: Avoid fullMDPComp[WithPTOR] on primary when secondary has YUV layer

* On Low end targets which has constraint on the #pipes, avoid
fullMDPComp and fullMDPCompWithPTOR on primary
when secondary is connected and secondary has a YUV layer.

* This helps in secondary have sufficient number of RGB or DMA pipes
to handle sudden increase in #layers.
