of: unittest: 64 bit dma address test requires arch support

[ Upstream commit 9fd4cf5d ]

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

Fixes: e0d07278 ("dma-mapping: introduce DMA range map, supplanting dma_pfn_offset")
