ACPI: Fix acpi_processor_idle and idle= boot parameters interaction
acpi_processor_idle and "idle=" boot parameter interaction is broken. The problem is that, at boot time acpi driver is checking for "idle=" boot option and not registering the acpi idle handler. But, when there is a CST changed callback (typically when switching AC <-> battery or suspend-resume) there are no checks for boot_option_idle_override and acpi idle handler tries to get installed with nasty side effects. With CPU_IDLE configured this issue causes results in a nasty oops on CST change callback and without CPU_IDLE there is no oops, but boot option of "idle=" gets ignored and acpi idle handler gets installed. Change the behavior to not do anything in acpi idle handler when there is a "idle=" boot option. Note that the problem is only there when "idle=" boot option is used.
