[PATCH] I2C: Allow for sharing of the interrupt line for i2c-mpc.c

I2C-MPC: Allow for sharing of the interrupt line

On the MPC8548 devices we have multiple I2C-MPC buses however they are on the
same interrupt line.  Made request_irq pass SA_SHIRQ now so the second bus can
register for the same IRQ.
