Starting from DG2 we will have resizable BAR support for device local-memory,
but in some cases the final BAR size might still be smaller than the total
local-memory size. In such cases only part of local-memory will be CPU
accessible, while the remainder is only accessible via the GPU. This series adds
the basic enablers needed to ensure that the entire local-memory range is
usable.

Needs to be applied on top of Arun' in-progress series[1].
