smsc911x: add support for platform-specific irq flags
this patch adds support for the platform_device's resources to indicate
additional flags to use when registering the irq, for example
IORESOURCE_IRQ_LOWLEVEL (which corresponds to IRQF_TRIGGER_LOW). These
should be set in the irq resource flags field.
