sched/irq: Add support interrupt chains in NuttX. IRQ chain is very useful in these cases: (1) Multiple hardware connect to the same request line(e.g. PCI), (2) Need multiple driver to support one hardware block (like Linux MFD)

spin_lock_irqsave() and spin_unlock_irqrestore() are only valid if the CPU supports global disabling of interrupts.

SMP: Introduce spin_lock_irqsave() and spin_unlock_irqrestore()
These APIs are simplified version of enter_critical_section() and
leave_critical_section() to protect data (e.g. registers) in SMP mode.
By using these APIs inside drivers, performace will be improved.

SMP: Back out deferred IRQ locking. This was accidentally merged into master and it looks like it is going to be more work than I thought to get it working again. Changes will go to the irqlock branch.
