platform/x86: ISST: Do Not Restore SST MSRs on CPU Online Operation
During CPU offline/online operations, the hardware retains MSR settings. Even if all CPUs are offlined, the package does not lose its MSR settings.
Therefore, it is unnecessary to restore MSRs which are modified during the online operation, and this extra step can be removed.

platform/x86: ISST: Support SST-PP revision 2
SST PP revision 2 added fabric 1 P0, P1 and Pm frequencies. Export them by using a new IOCTL ISST_IF_GET_PERF_LEVEL_FABRIC_INFO. This IOCTL requires platforms with SST PP revision 2 or higher.
To accommodate potential future increases in fabric count and avoid ABI changes, support is extended for up to 8 fabrics.
