of/unittest: Add dma-ranges address translation tests
The functions for parsing 'dma-ranges' ranges are buggy and fail to
handle several conditions. Add new tests for of_dma_get_range() and
for_each_of_pci_range().
With this test, we get 5 new failures which are fixed in subsequent
commits:
OF: translation of DMA address(0) to CPU address failed node(/testcase-data/address-tests/device@70000000)
FAIL of_unittest_dma_ranges_one():798 of_dma_get_range failed on node /testcase-data/address-tests/device@70000000 rc=-22
OF: translation of DMA address(10000000) to CPU address failed node(/testcase-data/address-tests/bus@80000000/device@1000)
