Read-back of 0x20ec (GEN9_CS_DEBUG_MODE1) seems to be causing issues. It 
could be put on the wo_register list if appropriate. And/or made 
RING_FORCE_TO_NONPRIV_RW.

However now I realize that handling of new whitelisting modes is missing 
from the selftest altogether. All RING_FORCE_TO_NONPRIV_RD and 
RING_FORCE_TO_NONPRIV_WR probably need explicit handling there - first 
ones to check they cannot be written to, and skip read-back on the 
second one.
