[PATCH 1/2] gpio: realtek-otto: use __raw_readl/writel in realtek_gpio_update_line_imr()

[Rustam Adilov]

In preparation for upcoming changes to how bank reads and writes
are defined in this driver, change the ioread32 and iowrite32 to
their __raw variants. The realtek_gpio_update_line_imr() function
is used by all devices regardless of GPIO_PORTS_REVERSED flag and
thus this is the only place where there shouldn't be any byte
swapping whether SWAP_IO_SPACE config is enabled or not and that
is only possible with __raw_readl and __raw_writel.
