Dma-buf is a standard cross-driver buffer sharing mechanism that can be
used to support peer-to-peer access from RDMA devices.

Device memory exported via dma-buf is associated with a file descriptor.
This is passed to the user space as a property associated with the buffer
allocation. When the buffer is registered as a memory region, the file
descriptor is passed to the RDMA driver along with other parameters.

Implement the common code for importing dma-buf object and mapping dma-buf
pages.

In order to improve performance by balancing the load between different
banks of cache, the CQC cache is desigend to choose one of 4 banks
according to lower 2 bits of CQN. The hns driver needs to count the number
of CQ on each bank and then assigns the CQ being created to the bank with
the minimum load first.

to do it, the user will get an error, but without any hint why. Update
nldev interface to return an error message through extack mechanism.
