dm: Fix error handling for dev_read_addr_ptr
dev_read_addr_ptr had different semantics depending on whether OF_LIVE was
enabled. This patch converts both implementations to return NULL on error,
and converts all call sites which check for FDT_ADDR_T_NONE to check for
NULL instead. This patch also removes the call to map_physmem, since we
have dev_remap_addr* for those semantics.
