Currently, we have a bug in opal-prd where we do not properly report
errors from xscom read/write ioctls returned from the kernel / firmware.
Patch 2 in this series fixes this issue.
However, we'd also like to report to HBRT that the fix is present. Patch
1 introduces a get_prd_flags() callback to the hostboot interface, to
allow indicications of variations in behaviour like the fix above.
Dan: this is a proposed change to struct host_interfaces, so we'll need
an Acked-by from your side before merging.
- rename callback to get_interface_capabilities
- implement capability sets
