MANA supports RDMA in PF mode. The driver should record the doorbell
physical address when in PF mode.

The doorbell physical address is used by the RDMA driver to map
doorbell pages of the device to user-mode applications through RDMA
verbs interface. In the past, they have been mapped to user-mode while
the device is in VF mode. With the support for PF mode implemented,
also expose those pages in PF mode.

It'd be good to indicate if the PF mode support is implemented as in
ready to be posted to the list, or implemented as in already in the
tree? If it's in tree then please quote the commit. If upcoming please
rephrase.

This commit msg is much better, thank you, but to a person handling
backports it will still not be immediately clear whether this is prep
work for a new code path, or a bug fix.
