Subject[PATCH] ACPI: processor_idle: delete use of NOP CPUIDLE_FLAGs
From: Len Brown <len.brown@intel.com>

CPUIDLE_FLAG_SHALLOW
CPUIDLE_FLAG_BALANCED
CPUIDLE_FLAG_DEEP
CPUIDLE_FLAG_CHECK_BM

were set by acpi_processor_setup_cpuidle(),
but never used by cpuidle or by acpi_idle.
So stop setting them.
