panic ibm4xx machines

Hi! all,


My OpenBlockS (evbppc) panics when boot time.

## Transferring control to NetBSD stage-2 loader (at address 00025000) ...
+40000000,
00025000-40000000 -> 00600000-40000000 = 3fa00000
panic: evcnt_attach_static: evcnt non initialized: group=<cpu> name=<tlbmiss>
Stopped in pid 0.1 (system) at  0x4d9e8:        lwz     r0, 0x14(r1)

I think this reason is:
http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/kern/subr_evcnt.c.diff?r1=1.7&r2=1.8&only_with_tag=MAIN&f=h

evcnt_attach_static() is called in
arch/powerpc/ibm4xx/pmap.c:pmap_bootstrap().


Please better fix.  ;-<
