pau: Add support for OpenCAPI Persistent Memory devices.
Lowest Point of Coherency (LPC) memory allows the host to access memory on
an OpenCAPI device.
When the P10 chip accesses memory addresses on the AFU, the Real Address
on the PowerBus must hit a BAR in the PAU such as GPU-Memory BAR. The BAR
defines the range of Real Addresses that represent AFU memory.
The two existing OPAL calls, OPAL_NPU_MEM_ALLOC and OPAL_NPU_MEM_RELEASE
are used to manage the AFU momory.
