powerpc/eeh: Introduce eeh_for_each_pe()
Add a for_each-style macro for iterating through PEs without the boilerplate required by a traversal function. eeh_pe_next() is now exported, as it is now used directly in place. Signed-off-by: Sam Bobroff <sbobroff@linux.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
