genirq: Generic chip: Change irq_reg_{readl,writel} arguments

Browse Source 
Pass in the irq_chip_generic struct so we can use different readl/writel
settings for each irqchip driver, when appropriate.  Compute
(gc->reg_base + reg_offset) in the helper function because this is pretty
much what all callers want to do anyway.

Compile-tested using the following configurations:

    at91_dt_defconfig (CONFIG_ATMEL_AIC_IRQ=y)
    sama5_defconfig (CONFIG_ATMEL_AIC5_IRQ=y)
    sunxi_defconfig (CONFIG_ARCH_SUNXI=y)

tb10x (ARC) is untested.
