x86, centaur: Enable cx8 for VIA Eden too
My box with following cpuinfo needs the cx8 enabling still:
vendor_id : CentaurHauls
cpu family : 6
model : 13
model name : VIA Eden Processor 1200MHz
stepping : 0
cpu MHz : 1199.940
cache size : 128 KB
This fixes valgrind to work on my box (it requires and checks
cx8 from cpuinfo).
