genirq: Generic chip: Allow irqchip drivers to override irq_reg_{readl,writel}
Currently, these I/O accessors always assume little endian 32-bit registers (readl/writel). On some systems the IRQ registers need to be accessed in BE mode or using 16-bit loads/stores, so we will provide a way to override the default behavior.
