pinctrl: microchip-sgpio: make irq_chip immutable

Browse source 
Since recently, the kernel is nagging about mutable irq_chips:

[    4.967050] gpio gpiochip1: (e2004190.gpio-input): not an immutable chip, please consider fixing it!

Drop the unneeded copy, flag it as IRQCHIP_IMMUTABLE, add the new
helper functions and call the appropriate gpiolib functions.
