irqchip: dw-apb-ictl: Add PM support
...
This patch adds in support for S2R for dw-apb-ictl irqchip driver.
We can used relaxed variants in the resume hook because there's no DMA
at all here, the device type memory attribute can ensure the operations
order and relaxed version imply compiler barrier.

irqchip: dw-apb-ictl: Enable IRQ_GC_MASK_CACHE_PER_TYPE
...
The irq_chip_type instances have separate mask registers, so we need to
enable IRQ_GC_MASK_CACHE_PER_TYPE to actually handle separate mask registers.

irqchip: dw-apb-ictl: Always use use {readl|writel}_relaxed
...
There's no DMA at all, the device type memory attribute can ensure the
operations order and relaxed version imply compiler barrier, so we are safe
to use relaxed version to improve the performance a bit.
