Frank Rowand 48d499bd89 of: unittest: overlay: ensure proper alignment of copied FDT 
The Devicetree standard specifies an 8 byte alignment of the FDT.
Code in libfdt expects this alignment for an FDT image in memory.
kmemdup() returns 4 byte alignment on openrisc.  Replace kmemdup()
with kmalloc(), align pointer, memcpy() to get proper alignment.

The 4 byte alignment exposed a related bug which triggered a crash
on openrisc with:
commit 79edff1206 ("scripts/dtc: Update to upstream version v1.6.0-51-g183df9e9c2b9")
