acpi-cpufreq: Fix some x86/x86-64 acpi-cpufreq driver issues

Browse Source 
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().
