patch

When i looked up register 0x00008040 i saw that it was defined as WAIT_UNTIL. 

The function that prints that error is 'evergreen_cs_check_reg' in
evergreen_cs.c. Since the WAIT_UNTIL is not present in reg_srcs/cayman (i have
a radeon 6950) the cayman_reg_safe_bm test fail and since WAIT_UNTIL is not
present in any of the switch cases it hits the default case.

But WAIT_UNTIL was present in reg_srcs/evergreen, so i copied the WAIT_UNTIL
line from evergreen to cayman. I also copied the rest of the WAIT_UNTIL_POLL*
because they seemed related.

This fixed the issue for me but i do not know if this is the proper fix.

Tested on kernel 3.8.0-rc5 and wayland/weston master and mesa master.
