This patch addresses some issues in x86/x86-64 acpi-cpufreq driver:
1. Current memory allocation for acpi_perf_data is actually open-coded
alloc_percpu(). The patch defines and handles acpi_perf_data as percpu
data. The code will be cleaner and easier to be maintained with this
change.
2. Won't load driver in acpi_cpufreq_early_init() failure case.
3. Add __init for acpi_cpufreq_early_init().
