Subject: [PATCH V2 0/3] Make the irqchip immutable

From: Cixi Geng <cixi.geng1@...soc.com>

Kernel warns about mutable irq_chips:
    "not an immutable chip, please consider fixing!"

Make the struct irq_chip const, flag it as IRQCHIP_IMMUTABLE, add the
new helper functions, and call the appropriate gpiolib functions.

changes:
split the patch by each driver. and other comment by baolin in[1]
