350929172b hw/rdma: Fix possible out of bounds access to regs array
Coverity (CID1390589, CID1390608).
Array size is RDMA_BAR1_REGS_SIZE, let's make sure the given address is
in range.

While there also:
1. Adjust the size of this bar to reasonable size
2. Report the size of the array with sizeof(array)

6f559013c8 hw/rdma: Fix 32-bit compilation
Use the correct printf formats, so that a 32-bit compile doesn't spit
out lots of warnings about %lx being incompatible with uint64_t.

0efc9511aa rdma: fix up include directives
Our rule right now is to use <> for external headers only.
RDMA code violates that, fix it up.

919ae3dd11 hw/rdma: Implementation of PVRDMA device
PVRDMA is the QEMU implementation of VMware's paravirtualized RDMA device.
It works with its Linux Kernel driver AS IS, no need for any special
guest modifications.

While it complies with the VMware device, it can also communicate with
bare metal RDMA-enabled machines and does not require an RDMA HCA in the
host, it can work with Soft-RoCE (rxe).

It does not require the whole guest RAM to be pinned allowing memory
over-commit and, even if not implemented yet, migration support will be
possible with some HW assistance.

Implementation is divided into 2 components, rdma general and pvRDMA
specific functions and structures.

The second PVRDMA sub-module - interaction with PCI layer.
- Device configuration and setup (MSIX, BARs etc).
- Setup of DSR (Device Shared Resources)
- Setup of device ring.
- Device management.
