ACPI: processor: idle: Convert acpi_processor_setup_cpuidle_states() to void

Browse Source 
Since all callers of acpi_processor_setup_cpuidle_states() ignore its
return value and it simply passes the acpi_processor_setup_lpi_states()
return value to its callers, convert both of these functions to void.

No intentional functional impact.
