Once opal-prd has finished initialisation (including loading &
initialising HBRT), we send an "init" message to OPAL, telling it that
we're listening on the PRD channel for events.
That init message includes the IPOLL bits that should be enabled, to
define the events that we can handle. That's what opal_prd_ipoll is.
Existing opal-prd hard-codes that to 0xf00...00. This change allows HBRT
to define that mask instead, using the get_ipoll_events() callback.
