soc/intel/tigerlake: Add IRQ mapping for PEG PCI-E ports
ACPI _PRT method was missing from PEG (SoC PCI-E) links, resulting in OS
complaining about interrupt routing.
'pcieport 0000:00:06.0: can't derive routing for PCI INT A'
'nvme 0000:04:00.0: PCI INT A: not connected'
'Interrupt: pin A routed to IRQ -2147483648'
TEST=Boot Linux and Windows 10 on TGL-H platform with PEG0/PEG1
populated with PCI-E devices - Radeon RX 7800XT and Kingston KC3000 NVME
SSD. Check logs and stability while running 3D application and disk
benchmark at the same time.
