[PATCH] smc91x needs settable IRQ trigger type
For boards that invert the SMC91x IRQ line (maybe an FPGA inverts it), the set_irq_type() call can't assume IRQT_RISING. These particular boards currently use OMAP-specific calls to change the trigger type, but the boards break when set_irq_type() stops being a NOP.
