of: unittest: fix warning on PowerPC frame size warning 

[ Upstream commit a8d61a9112ad0c9216ab45d050991e07bc4f3408 ]

The struct device variable "dev_bogus" was triggering this warning
on a PowerPC build:

    drivers/of/unittest.c: In function 'of_unittest_dma_ranges_one.constprop':
    [...] >> The frame size of 1424 bytes is larger than 1024 bytes
             [-Wframe-larger-than=]

This variable is now dynamically allocated.

Fixes: e0d072782c ("dma-mapping: introduce DMA range map, supplanting dma_pfn_offset")
