powerpc/t4240: Adding workaround errata A-005871
When CoreNet Fabric (CCF) internal resources are consumed by the cores,
inbound SRIO messaging traffic through RMan can put the device into a
deadlock condition.
This errata workaround forces internal resources to be reserved for
upstream transactions. This ensures resources exist on the device for
upstream transactions and removes the deadlock condition.
The Workaround is for the T4240 silicon rev 1.0.
