ACPI: CPPC: Fix remaining for_each_possible_cpu() to use online CPUs
per_cpu(cpc_desc_ptr, cpu) object is initialized for only the online
CPUs via acpi_soft_cpu_online() --> __acpi_processor_start() -->
acpi_cppc_processor_probe().
However, send_pcc_cmd() and acpi_get_psd_map() still iterate over all
possible CPUs. In acpi_get_psd_map(), encountering an offline CPU
returns -EFAULT, causing cppc_cpufreq initialization to fail.
This breaks systems booted with "nosmt" or "nosmt=force".
Fix by using for_each_online_cpu() in both functions.
