If one enables ION_DUMMY_UNMAPPED_HEAP without providing the target
unmapped heap configuration settings (physical base address and size),
the kernel cannot build. This situation occurs in linux test build
cases, i.e running the allmodconfig configuration.
This change overcomes the issue by providing default null settings both
ION_DUMMY_UNMAPPED_BASE and ION_DUMMY_UNMAPPED_SIZE.
