ion: fix unmapped heap test settings **not for mainline**
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 for
both ION_DUMMY_UNMAPPED_BASE and ION_DUMMY_UNMAPPED_SIZE.

ion: unmapped heap support in ion dummy driver **not for mainline**

ion: "unmapped" heap for secure data path **not for mainline**
OP-TEE/SDP (Secure Data Path) memory pools are created through ION

"unmapped" as, from Linux point of view, the heap constraint is

"Unmapped" heap support is integrated in ION UAPI (actually this was
the Allwinner initial proposal) and ION DT parsing support.
