of: unittest: fix warning on PowerPC frame size warning
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.
