[PATCH V2] of: reserved-memory: ignore disabled memory-region nodes

From: Krishna Reddy <vdumpa@nvidia.com>

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.

v2:
* Fixed typo in commit message.
* Used "of_device_is_available" to check "reserved-memory"
nodes are disabled/enabled.
