Platforms like ARM Ltd's RealView require the IRQ polarity bit to be set
for the SMC9118 chip. This patch allows the dynamic configuration via
the smc911x_platdata structure.
This patch also changes the smc91x_platdata structure name to the
correct smc911x_platdata in the smc911x_drv_probe() function.
