[Skiboot] [PATCH 1/2] opal-prd: Add get_prd_flags to host interfaces

Yes, this is intended to cover more than fixes; "capabilities" would be
a better term here.

For example, if this was present during the change to add the 'instance'
parameter to get_reserved_mem(), we would have indicated this as a
capability bit. [It so happened that the semantics of the call meant
could implement that in an ABI-backwards-compatible way, but we got
lucky with that]

So, how is:

  get_interface_capabilities()

?

Yep, we'd need to keep that in sync.

Cheers,
