Align the parameters of gdb_get_reg_cb and gdb_set_reg_cb with the
gdb_read_register and gdb_write_register members of CPUClass to allow
to unify the logic to access registers of the core and coprocessors
in the future.

It looks like virtio-pci is entirely broke in qemu-system-arm, at least in tcg
mode running on x86. The guest (current linux system) just does not detect
any virtio-pci devices at all.
When 8.1 is booting, the following messages are displayed (debian initramfs):

It will hold properties shared among all vhost_vdpa instances associated

It is always VHOST_IOTLB_MSG_V2. We can always make it back per
vhost_dev if needed.
This change makes easier for vhost_vdpa_map and unmap not to depend on
vhost_vdpa but only in VhostVDPAShared.

There's no need to explicitely allocate the memory here, we can
simply embed it into the m5206_mbar_state instead.
