powerpc/eeh_cache: Add pr_debug() prints for insert/remove
The EEH address cache is used to map a physical MMIO address back to a PCI
device. It's useful to know when it's being manipulated, but currently this
requires recompiling with #define DEBUG set. This is pointless since we
have dynamic_debug nowdays, so remove the #ifdef guard and add a pr_debug()
for the remove case too.
