Trap EL1 accesses to Statistical Profling Extension registers Statistical Profiling Extention (SPE) registers could expose side-channels. Hafnium would also need to implement a proper context switching to handle them. Trap accesses until there is an SPE-capable target on the horizon. Bug: 141600635 Change-Id: Ia5bf5b20411735abfdd9042e8c93d5b12f578506
