fix(pmu): add sensible default for MDCR_EL2 When TF-A is set to save and restore EL2 registers it initially zeroes all of them so that it does not leak any information. However, MDCR_EL2.HPMN of 0 is poorly defined when FEAT_HPMN0 is not implemented. Set it to its hardware reset value so that lower ELs don't inherit a wrong value.
