If DSC is enabled, the only case is with 2 DSC engines so far. And
DSC in all pipes are configured by default.

More usage case will be added, such as 4 DSC in 4:4:2 topoplogy.
Pipe number is extended in future to support quad-pipe. But only
some of 4 pipes are used in non quad-pipe. So number of DSC is
not aligned with maximum pipes.

Thus we support DSC flexiblely with this patch set with storing
the number and configuring DSC with it.
