Revert "radeonsi: disable DCC on Stoney"

This reverts commit 32f05fadbbdf2a3fb60055e610bbbdcd82dd3ce5.

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.
