PAGE_OFFSET and __pa() are always available, so use them to get the physical start of memory address. This should have probably used 'dma-ranges' to get the address, but we don't want to force a DT update to do that. At least in QEMU, the SMAP registers have no effect (or perhaps the only value that is handled is 0).
