Subject: [PATCH v3 net-next 1/9] net: devlink: regions: Add a priv member to the regions ops struct

The driver may have multiple regions which can be dumped using one
function. However, for this to work, additional information is
needed. Add a priv member to the ops structure for the driver to use
however it likes.
