mfd: Use platform_get_irq() to get the interrupt
It is not recommened to use platform_get_resource(pdev, IORESOURCE_IRQ) for requesting IRQ's resources any more, as they can be not ready yet in case of DT-booting. platform_get_irq() instead is a recommended way for getting IRQ even if it was not retrieved earlier. It also makes code simpler because we're getting "int" value right away and no conversion from resource to int is required. The print function dev_err() is redundant because platform_get_irq() already prints an error.
