for_each_child_of_node performs an of_node_get on each iteration, so
a break out of the loop requires an of_node_put.

A simplified version of the semantic patch that fixes this problem is as
follows (http://coccinelle.lip6.fr):

// <smpl>
@@
expression root,e;
local idexpression child;
@@

 for_each_child_of_node(root, child) {
   ... when != of_node_put(child)
       when != e = child
(
   return child;
|
+  of_node_put(child);
?  return ...;
)
   ...
 }
// </smpl>

Combine the puts into code at the end of the function, for conciseness.

This patch allows PCI host controller to function even if part of resources
is unusable for some reason. An example is non-LPAE kernel on a machine
which has some 64-bit resources. Unusable resources will be just skipped
instead of a complete failure.
Signed-off-by: Pavel Fedin <p.fedin@samsung.com>
Signed-off-by: Rob Herring <robh@kernel.org>

If non-LPAE kernel is booted up on a machine with 64-bit PCI resources,
PCI controller probe fails with:

PCI host bridge /pcie@10000000 ranges:
   IO 0x3eff0000..0x3effffff -> 0x00000000
  MEM 0x10000000..0x3efeffff -> 0x10000000
  MEM 0x8000000000..0xffffffffff -> 0x8000000000
pci-host-generic 3f000000.pcie: resource collision: [mem 0x00000000-0xffffffff] conflicts with /pl011@9000000 [mem 0x09000000-0x09000fff]
pci-host-generic: probe of 3f000000.pcie failed with error -16

This happens because res->start assignment in of_pci_range_to_resource()
truncates the upper part of the address, because res->start is of
phys_addr_t type, which is 32-bit on non-LPAE kernels.

This patch adds explicit recognition of 64-bit resources, preventing from
potential problems when e. g. 0x8000001234 would be converted to
0x00001234.
