[Why]
Due Page faults can easily overwhelm the interrupt handler.
So to make sure that we never lose valuable interrupts on the primary ring
we re-route page faults to IH ring 1.
It also facilitates the recovery page process, since it's already
running from a process context.
This is valid for Arcturus and future Navi generation GPUs.
[How]
Setting IH_CLIENT_CFG_DATA for VMC and UMD IH clients.

This change seems to break the sequence of IP block initialization that
is special for SRIOV. Is your intention to use the SRIOV sequence for
bare metal as well? That would be good for simplifying the code but then
that should be stated in the commit description, or even be done as a
separate commit.
See this commit for reference:
