ACPI: CPPC: Clean up cppc_perf_caps and cppc_perf_ctrls structs

 - Remove redundant energy_perf field from 'struct cppc_perf_caps' as
   the same is available in 'struct cppc_perf_ctrls' which is used.

 - Move the 'auto_sel' field from 'struct cppc_perf_caps' to
   'struct cppc_perf_ctrls' as it represents a control register.
