Out of curiosity, none of the other qdss stuff is in here, why this
specifically?

In previous pinctrls, we've done one group for active high and one group for
active low of the same signal. If you follow that, one would be pci_e0 and the
other would be pci_e0_n. You need to have them different groups.

So add the relevant groups/functions mentioned above to match up to the previous
pinctrl drivers. This makes it consistent across the different chips to the
extent that we can make it consistent.
