Glenn Miles c6e07f03f7 ppc/pnv: Fix loss of LPC SERIRQ interrupts 
The LPC HC irq status register bits are set when an LPC IRQSER input is
asserted. These irq status bits drive the PSI irq to the CPU interrupt
controller. The LPC HC irq status bits are cleared by software writing
to the register with 1's for the bits to clear.

Existing register write was clearing the irq status bits even when the
input was asserted, this results in interrupts being lost.

This fix changes the behavior to keep track of the device IRQ status
in internal state that is separate from the irq status register, and
only allowing the irq status bits to be cleared if the associated
input is not asserted.
