[PATCH] mfd: da9052-core: Fix request_threaded_irq() parameter

[Fabio Estevam <festevam@gmail.com>]

From: Fabio Estevam <fabio.estevam@freescale.com>

On a mx53qsb dt-kernel the da9052-core driver fails to probe:

da9052 1-0048: DA9052 ADC IRQ failed ret=-22

In request_threaded_irq() the first parameter is missing the da9052->irq_base.

Fix it and avoid the error.

Also define 'DA9052_IRQF' for improving readability.
