These patches try to improve dw-apb-ictl irqchip driver a bit.

The first patch improves the performance a bit -- use the relaxed version

The two dw-apb-ictl's irq_chip_type instances have separate mask registers, so the second patch enables IRQ_GC_MASK_CACHE_PER_TYPE.

The last patch adds suspend/resume support to the driver.

Tested on Marvell BG2Q-DMP board.

Changes in v2:
  - Add Sebastian's Acks
  - Update the first commit as Sebastian and Thomas suggested
  - Add into commit log summary of the discussion why relaxed variants can be used

Jisheng Zhang (3):
  irqchip: dw-apb-ictl: always use use {readl|writel}_relaxed
  irqchip: dw-apb-ictl: enable IRQ_GC_MASK_CACHE_PER_TYPE
  irqchip: dw-apb-ictl: add PM support
