Subject: [PATCH] ACPI: processor_idle: delete use of NOP CPUIDLE_FLAGs

From: Len Brown <len.brown@...el.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.
