powerpc/cacheinfo: Use name@unit instead of full DT path in debug messages

We know that every OF node we deal with in this code is under /cpus,
so we can make the debug messages a little less verbose without losing
information.

E.g.

cacheinfo: creating L1 dcache and icache for /cpus/PowerPC,POWER8@0
cacheinfo: creating L2 ucache for /cpus/l2-cache@2006
cacheinfo: creating L3 ucache for /cpus/l3-cache@3106

becomes

cacheinfo: creating L1 dcache and icache for PowerPC,POWER8@0
cacheinfo: creating L2 ucache for l2-cache@2006
cacheinfo: creating L3 ucache for l3-cache@3106

Replace all '%pOF' specifiers with '%pOFP'.
