When calling request IRQ it is desirable to allow platforms
to specific flags for the call to request_irq. Adding irq_flags
to smsc911x_platform_config allows these flags to be passed.

If you need shared interrupt support, pass always pass IRQF_SHARED.
IRQF_SHARED and IRQF_DISABLED are a property of the driver.

Edge/level configuration should come from the struct resource.
