Subject: [PATCH 2/2] gpiolib: of: add polarity quirk for Freescale PCIe controller

Bindings for Freescale PCIe controller use a separate property called
"reset-gpio-active-high" to control polarity of its reset line, add it
to the list of quirks in gpiolib so that gpiod API can be used in the
driver.
