drm/radeon: Changing number of compute pipe lines

commit e405ca3a1bf166f741506c07c2a277b5d48af8f7 upstream.

The current CP firmware can handle Usermode Queues only on MEC1.
To reflect this firmware change, this commit reduces number of compute pipelines
to 4 - 1, from 8 - 1 (the first pipeline is allocated for kgd).
