ACPI: processor: idle: Rework the handling of acpi_processor_ffh_lpi_probe()

Browse Source 
Move the acpi_processor_ffh_lpi_probe() call from
acpi_processor_setup_cpuidle_dev(), where its return value is
ignored, to acpi_processor_get_power_info(), which can take the
return value of that function into account in a meaningful way
and generally is a more suitable place for calling it.
