powerpc/eeh: Build EEH event based on PE
The original implementation builds EEH event based on EEH device. We already had dedicated struct to depict PE. It's reasonable to build EEH event based on PE. Signed-off-by: Gavin Shan <shangw@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
