Subject: [PATCH v2 0/2] irqchip: dw-apb-ictl: add irq_set_affinity support

On Marvell Berlin SoCs, the cpu's local timer is shutdown when the cpu
goes to a deep idle state, then the timer framework will be notified to
use a broadcast timer instead. The broadcast timer uses dw-apb-ictl as
interrupt chip, these patches try to add irq_set_affinity support so
that the going to deep idle state cpu can set the interrupt affinity of the
broadcast interrupt to avoid unnecessary wakeups and IPIs.

Changes since v1:
 - Add a simple test and its result into the second patch's commit msg.

  irqchip: dw-apb-ictl: add private data structure
  irqchip: dw-apb-ictl: add irq_set_affinity support
