ARCv2: MCIP: Deprecate setting of affinity in Device Tree
Ignore value of interrupt distribution mode for common interrupts in IDU since setting of affinity using value from Device Tree is deprecated in ARC. Originally it is done in idu_irq_xlate() function and it is semantically wrong and does not guaranty that an affinity value will be set properly. idu_irq_enable() function is better place for initialization of common interrupts. By default send all common interrupts to all available online CPUs. The affinity of common interrupts in IDU must be set manually since in some cases the kernel will not call irq_set_affinity() by itself: 1. When the kernel is not configured with support of SMP. 2. When the kernel is configured with support of SMP but upper interrupt controllers does not support setting of the affinity and cannot propagate it to IDU.
