The call to early_init_fdt_scan_reserved_mem will be skipped if
reserved-ranges is not found. Move the call earlier so that it is called

Currently, on 8641D, which doesn't set CONFIG_HAVE_HW_BREAKPOINT
we get the following splat:

It may not when it runs uninterrupted but after the tracee process has stopped,
thread.dscr reflects the default DSCR value as mentioned before. This can b

That's not what that patch does. It shouldn't make any user visible changes
to DSCR or PPR.
Over syscall PPR and DSCR may change. Depending on your test case, that may
be your problem.

As Ben suggested, it's meaningful to dump PE's location code
for site engineers when hitting EEH errors. The patch introduces
function eeh_pe_loc_get() to retireve the location code from
dev-tree so that we can output it when hitting EEH errors.
