arm64: cpuidle: fix #ifdef for acpi functions
The acpi_processor_ffh_lpi_* functions are defined whenever CONFIG_ACPI
is enabled, but only called and declared when CONFIG_ACPI_PROCESSOR_IDLE
is also enabled. Without that, a W=1 build triggers missing-prototope
warnings, so the #ifdef needs to be adapted:
arch/arm64/kernel/cpuidle.c:60:5: error: no previous prototype for 'acpi_processor_ffh_lpi_probe' [-Werror=missing-prototypes]
arch/arm64/kernel/cpuidle.c:65:15: error: no previous prototype for 'acpi_processor_ffh_lpi_enter' [-Werror=missing-prototypes]
