[PATCH 1/1] of: unittest: 64 bit dma address test requires arch support

[frowand . list]

From: Frank Rowand <frank.rowand@xxxxxxxx>

If an architecture does not support 64 bit dma addresses then testing
for an expected dma address >= 0x100000000 will fail.

Fixes: e0d072782c73 ("dma-mapping: introduce DMA range map, supplanting dma_pfn_offset")
