soc/intel/tgl: Add PEG devices to PCI constraints
Based on the constraints for CML.
Fixes the following warnings in Linux on system76/oryp8 and
system76/gaze16, which have an NVIDIA GPU on the bridge.
pcieport 0000:00:01.0: can't derive routing for PCI INT A
pcieport 0000:00:01.0: can't derive routing for PCI INT B
This, in turn, resolves an IRQ conflict with the PCH HDA device that
would cause a stack trace on every boot and on S3 suspend.
irq 10: nobody cared (try booting with the "irqpoll" option)
<snip>
[<00000000fb84c354>] azx_interrupt [snd_hda_codec]
Disabling IRQ #10
