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

From: Frank Rowand <[email protected]>

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")
