[PATCH] yenta: interrupt routing for TI briges

Some TI cardbus bridges found in notebooks and PCI add-on cards are
uninitialized.  This means the interrupt mode and the interrupt routing
is wrong in most cases, ending up in non working PCI interrupts.

This makes the TI Yenta driver probe the PCI interrupt and adjust the
interrupt setting if no interrupts are delivered.  It's done in a safe
way, that doesn't hurt working setups.

Function 1 on two slot devices is handled differently from function 0
since both share the settings.
