x86: Add IRQF_TIMER to legacy x86 timer interrupt descriptors
Right now nobody cares, but the suspend/resume code will eventually want to suspend device interrupts without suspending the timer, and will depend on this flag to know. The modern x86 timer infrastructure uses the local APIC timers and never shows up as a device interrupt at all, so it isn't affected and doesn't need any of this. Cc: Rafael J.
