Create an anonymous output GPIO line to connect the LPC device with the PSIHB device and raise the appropriate PSI IRQ line depending on the processor model. A temporary __pnv_psi_irq_set() routine is introduced to handle the transition. It will be removed when all devices raising PSI interrupts are converted to use GPIOs.
