Why would you not want it? I see other SOC PCI controllers are also
enabled. I would like to have it because we have an Intel e1000 on our
pitx-imx8m board and the seconds PCI slot is for a m.2 card. So we
would have the PCI support with the default defconfig. On the NXP
imx8mq EVK a m.2 is connected to the PCI interface.

Is this the kind of comments you want?
