[PATCH] ARM: prima2: return rather than panic on missing DT nodes

[robherring2@gmail.com (Rob Herring)]

From: Rob Herring <rob.herring@calxeda.com>

Missing nodes is a normal condition in multi-platform kernels when we boot
on other platforms. So remove the panic and just return if we don't find
a DT node.
