While parsing "memory-region" node lists if a node is
"disabled", parsing halts. Therefore the nodes whose
"status" is "okay" or "ok" are not parsed.
The change ignores disabled nodes in the memory-region
nodes list and returns 0 to continue parsing next nodes.

v2:
* Fixed typo in commit message.
* Used of_device_is_available to check device is disabled/enabled.

Ignore disabled nodes in the memory-region
nodes list and continue to initialize the rest
of enabled nodes.
Check if the "reserved-memory" node is available
and if it's not available, return 0 to ignore the
"reserved-memory" node and continue parsing with
next node in memory-region nodes list.
