This fixes a failure with the improved Piglit user-test clip in bug 31787
(problem originally discovered in Clutter conformance test suite)
This makes the r600 registers correspond between r600c and r600g. The
corresponding evergreen code uses a stride of 4 for both r600c and r600g -
from the register locations it doesn't appear that can be correct but
without hardware or docs at hand, I didn't want to change it in this
patch. Should be checked.

r600g: Fix location for clip plane registers
The stride between the different clip plane registers was incorrect.
Evergreen needs the fix as well, and I added it. For reference, you can find the evergreen regs here:
