irqchip/irq-realtek-rtl: Use readl_be()/writel_be() instead of readl()/writel()

Browse source

When CONFIG_SWAP_IO_SPACE is enabled, readl() performs a swap from little
endian device to big endian CPU and vice versa for writel().

This is incorrect for Realtek Interrupt controller as that is a big endian
device and so the LE to BE conversions are unwanted.

Fix this by converting the MMIO accesses to readl_be() and writel_be().
