hw/i386/pc_q35: Populate interrupt handlers before realizing LPC PCI function

The interrupt handlers need to be populated before the device is realized since
internal devices such as the RTC are wired during realize(). If the interrupt
handlers aren't populated, devices such as the RTC will be wired with a NULL
interrupt handler, i.e. MC146818RtcState::irq is NULL.
