The system register actlr_el2 can be set during CPU or platform reset
handler. E.g. on Arm Total Compute platform, the CLUSTERPMUEN bit of
actlr_el2 is set in the platform reset handler to enable the write
access to DSU PMU registers from EL1. However, as EL2 context gets
restored without saving it beforehand during jump to SPM and next NS
image, therefore, the initialized value of actlr_el2 is not retained.
To fix this issue, keep track of actlr_el2 value during the EL2 context
initialization. This applies for both secure and non-secure security
state.
