Add Dmitry and Bartosz.

Hi Krzysztof,
Seems this property is still handled in gpiolib-of.c, see commit b8b80348c57b
("gpiolib: of: add polarity quirk for Freescale PCIe controller").
Maybe need to change the quirk gpio_propname here too.

 Also change the "reset-gpio" to "reset-gpios" in this description.

Best Regards
