RAS errors can cause problems for powerdown. On cpus like the A510, receiving a RAS error after executing the powerdown `wfi` will deadlock the core. The TRM suggests disabling the generation of interrupts. However, which interrupts to disable is not apparent for generic code as the meaning of each error record is *heavily* IMPDEF, despite the standard format. Iterating over the list and disabling all is not desirable as this might disable errors for components that do not have an effect on the core that is powering down. As such, leave this for the platform port to handle. Leave a note in the porting guide so this is not missed.
