Our field definitions for CTR_EL0 suffer from a number of problems:
The IDC and DIC fields are missing, which causes us to enable CTR trapping on CPUs with either of these returning non-zero values.
The ERG is FTR_LOWER_SAFE, whereas it should be treated like CWG as FTR_HIGHER_SAFE so that applications can use it to avoid false sharing.
[nit] A RES1 field is described as "RAO"
This patch updates the CTR_EL0 field definitions to fix these issues.
