[PATCH -next] ACPI: CPPC: Fix some kernel-doc comments

[Yang Li]

Add the description of @pcc_ss_id in pcc_data_alloc().
Add the description of @cpu_num in cppc_get_transition_latency().

clear the below warnings:
drivers/acpi/cppc_acpi.c:607: warning: Function parameter or member 'pcc_ss_id' not described in 'pcc_data_alloc'
drivers/acpi/cppc_acpi.c:1616: warning: Function parameter or member 'cpu_num' not described in 'cppc_get_transition_latency'
