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.
