[ARM] 3530/1: PXA Mainstone: prevent double enable_irq() in pcmcia

Patch from Thomas Gleixner

The mainstone board pcmcia interrupt have been enabled via setup_irq()
and the following socket check calls enable_irq again. Set the NOAUTOEN flag so the interrupt is not automatically enabled in setup_irq()
