drm/radeon: fix render backend setup for SI and CIK

Only the render backends of the first shader engine were enabled. The others
were erroneously disabled. Enabling the other render backends improves
performance a lot.

Unigine Sanctuary on Bonaire:
  Before: 15 fps
  After:  90 fps

Judging from the fan noise, the GPU was also underclocked when the other
render backends were disabled, resulting in horrible performance. The fan is
a lot noisy under load now.

drm/radeon: expose render backend mask to the userspace

This will allow userspace to correctly program the PA_SC_RASTER_CONFIG
register, so it can be considered a fix.

drm/radeon: set correct number of banks for CIK chips in DCE

We don't have the NUM_BANKS parameter, so we have to calculate it
from the other parameters. NUM_BANKS is not constant on CIK.

This fixes 2D tiling for the display engine on CIK.
