of/flattree: Fix unhandled OF_DT_NOP tag when unflattening the device tree
NOPs within the property section are skipped, but NOPs between
OF_DT_END_NODE and OF_DT_BEGIN_NODE were not. My firmware NOPs out
entire nodes depending on various environment parameters.
of_scan_flat_dt already handles NOP more generally.
