[PATCH] mfd: sun4i-gpadc: adaptation interrupt number

[Fuyao Kashizuku]

The identifiers are used as IRQ resource numbers, where 0 is treated
specially.

This fixes sun4i-gpadc-iio probe failed when request irq.

The backstack:
	WARNING: CPU: 3 PID: 1 at drivers/base/platform.c:451
	__platform_get_irq_byname+0xb8/0xc4
	0 is an invalid IRQ number
	Modules linked in:
