Cze??,

I wonder if all boards (except maybe that Toradex set) use an
active-low
PCIe reset and are now broken. Perhaps Toradex uses active-high and
thus
works.

I'm really puzzled by this :-) With your patch applied I get
following on
Toradex Apalis modules:

?DTS:?????????reset-gpio = <&gpio1 28 GPIO_ACTIVE_LOW>;
?dmesg:???????imx6q-pcie 1ffc000.pcie: phy link never came up
?gpio:????????gpio-28??(????????????????????|reset???????????????)
out hi
?pin voltage: 0V

?DTS:?????????reset-gpio = <&gpio1 28 GPIO_ACTIVE_HIGH>;
?dmesg:???????ath9k 0000:01:00.0: enabling device (0140 -> 0142)
?gpio:????????gpio-28??(????????????????????|reset???????????????)
out lo
?pin voltage: 3V3

So Toradex Apalis is actually active-high?

Yes, I actually explained this in detail in my cover letter:
