Revert "radeonsi: disable DCC on Stoney"

Browse Source 
This reverts commit 32f05fadbb.

It turned out the problem with Stoney was caused by incorrect handling of
a non-power-two VRAM size in the kernel driver.
This is an optional BIOS setting and can be worked around by choosing
a different VRAM size in the BIOS.
