cpufreq: CPPC: Add generic helpers for sysfs show/store
Add generic helper functions for u64 sysfs attributes that follow the
common pattern of calling CPPC get/set APIs:
- cppc_cpufreq_sysfs_show_u64(): reads value and handles -EOPNOTSUPP
- cppc_cpufreq_sysfs_store_u64(): parses input and calls set function
Add CPPC_CPUFREQ_ATTR_RW_U64() macro to generate show/store functions
using these helpers, reducing boilerplate for simple attributes.
Convert auto_act_window and energy_performance_preference_val to use
the new macro.
No functional changes.
