Nikhil P. Rao b311af86b5 pds_core: add host backed memory support for firmware ...

Some newer AMD/Pensando cards have minimal memory and there are cases
where components, specifically in the control plane, need more memory.
This series adds support for host backed DMA memory that can be used
by the firmware for the previously mentioned cases.

Host memory allocation is best-effort: if some allocations fail, the
driver continues with whatever succeeded. Firmware gracefully degrades
when less memory is available than requested.
