Moved, renamed, and deleted files

The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

- * These flags used only by the kernel as part of the

- *
- * IRQF_DISABLED - keep irqs disabled when calling the action handler.
- *                 DEPRECATED. This flag is a NOOP and scheduled to be removed
- * IRQF_SAMPLE_RANDOM - irq is used to feed the random generator
- * IRQF_SHARED - allow sharing the irq among several devices
- * IRQF_PROBE_SHARED - set by callers when they expect sharing mismatches to occur
- * IRQF_TIMER - Flag to mark this interrupt as timer interrupt
- * IRQF_PERCPU - Interrupt is per cpu
- * IRQF_NOBALANCING - Flag to exclude this interrupt from irq balancing
- * IRQF_IRQPOLL - Interrupt is used for polling (only the interrupt that is
- *                registered first in an shared interrupt is considered for
- *                performance reasons)
- * IRQF_ONESHOT - Interrupt is not reenabled after the hardirq handler finished.
- *                Used by threaded interrupts which need to keep the
- *                irq line disabled until the threaded handler has been run.
- * IRQF_NO_SUSPEND - Do not disable this IRQ during suspend
- * IRQF_FORCE_RESUME - Force enable it on resume even if IRQF_NO_SUSPEND is set
- * IRQF_NO_THREAD - Interrupt cannot be threaded
- * IRQF_EARLY_RESUME - Resume IRQ early during syscore instead of at device
- *                resume time.
