iommu: Add DMA window parser, of_get_dma_window()
This code was based on:
"arch/microblaze/kernel/prom_parse.c"
"arch/powerpc/kernel/prom_parse.c"
Can replace "of_parse_dma_window()" in the above. This supports
different formats flexibly. "prefix" can be configured if any. "busno"
and "index" are optionally specified. Set NULL and 0 if not used.
