In an effort to simplify the core idle path, move any device-specific special case handling from the core PM idle path into the CPUidle pre-idle checking path. This keeps the core, interrupts-disabled idle path streamlined and independent of any device-specific handling, and also allows CPUidle to do the checking only for certain C-states as needed. This patch has the device checks in place for all states with the CHECK_BM flag, namely all states >= C2. This patch was inspired by a similar patch written by Tero Kristo as part of a larger series to add INACTIVE state support. NOTE: This is a baby-step towards decoupling device idle (or system idle) from CPU idle. Eventually, CPUidle should only manage the CPU, and device/system idle should be managed elsewhere.
