This feels like the bug that simply won't go away however I did a test
build of r345425 and no amount of coaxing nor kern.smp.disabled would
get past fans roaring after seeing a wake up call to CPU3. A step back
to r344744 seems to work fine provided that one provide the usefdt=1
and then boot -sv :

hydra$ uname -a 
FreeBSD hydra 13.0-CURRENT FreeBSD 13.0-CURRENT r344744 GENERIC  powerpc
hydra$ sysctl -a kern.smp.cpus
kern.smp.cpus: 4
hydra$ 

Also bge0 and bge1 network interfaces are reversed however this is 
merely an annoyance : 

bge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
       
options=8009b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,LINKSTATE>
        ether 00:14:51:64:67:11
        inet 172.16.35.8 netmask 0xffffffc0 broadcast 172.16.35.63
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
        media: Ethernet autoselect (1000baseT <full-duplex,master>)
        status: active
bge1: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
       
options=8009b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,LINKSTATE>
        ether 00:14:51:64:67:10
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
        media: Ethernet autoselect
