[PATCH v2 3/3] lsslot: fix reporting of L3 caches with -b option

[Tyrel Datwyler]

Currently if a L2 cache has an associated dependent L3 cache the lsslot
command for cpu connector types will fail to report the L3 cache when
using the -b option. This is due to a typo such that the check is made
between the the L2 caches l2-cache property value and its own
ibm,phandle property. The check should be against the L3 caches
ibm,phandle property as the l2-cache property contains the phandle of
the dependent cache.

Without patch:
./src/drmgr/lsslot -c cpu -b
drc-name OFDT-node drc_index thread id(s) l2-cache l3-cache
CPU 1 PowerPC,POWER8@0 10000000 0 1 2 3 4 5 6 7 l2-cache@200a N/A

With patch:
./src/drmgr/lsslot -c cpu -b
drc-name OFDT-node drc_index thread id(s) l2-cache l3-cache
CPU 1 PowerPC,POWER8@0 10000000 0 1 2 3 4 5 6 7 l2-cache@200a l3-cache@310a
