The sandbox iommu driver uses the LMB module to allocate a particular range of memory for the device virtual address(DVA). This used to work earlier since the LMB memory map was caller specific and not global. But with the change to make the LMB allocations global and persistent, adding this memory range has other side effects. On the other hand, the sandbox iommu test expects to see this particular value of the DVA. Use the DVA address directly, instead of mapping it in the LMB memory map, and then have it allocated.

Changes since V1:
- Move the DVA address and page size as macros to the test.h header file.
