Do not register any IRQ handler for IRQ_WAKE_SGI
The timer management framework uses SGI number 'IRQ_WAKE_SGI'
as the way to notify CPUs when the system timer fires off.
Therefore, this SGI needs to be enabled on all CPUs. However,
there is no need to register a particular handler for this IRQ.
Also, the choice of SGI used by the timer management framework is
not platform-specific. Therefore, the definition of the constant
'IRQ_WAKE_SGI' is moved to the generic header file 'irq.h'.
