mb/google/kahlee/mainboard.c: Create mainboard_pirq_data
When booting kahlee, there's an error message: "Warning: Can't write PCI IRQ assignments because 'mainboard_pirq_data' structure does not exist". This is generated by write_pci_cfg_irqs due to missing mainboard_pirq_data. BUG=b:70788755 TEST=Build and boot kahlee. Warning message must be gone.
