[PATCH 4/7] iio:adc:sun4i-gpadc: Use new IRQF_NO_AUTOEN flag instead of request then disable

[Jonathan Cameron <jic23@kernel.org>]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

This new flag ensures a requested irq is not autoenabled, thus removing
the need for the disable_irq() that follows and closing off any chance
of spurious interrupts.
