[PATCH] i.MX6 PCIe: Fix imx6_pcie_deassert_core_reset() polarity

Fabio Estevam [off-list ref] writes:

In order to keep old dtb's working we should simply ignore the GPIO
flags passed in the 'reset-gpio' property.

That's why we need a revert. Just sent a v2, BTW.

OTOH, we should fix it some day, making sure the DTS files are fixed
first:

imx6qdl-apf6dev.dtsi:       reset-gpio = <&gpio6 2 GPIO_ACTIVE_HIGH>;
imx6qdl-aristainetos2.dtsi: reset-gpio = <&gpio2 16 GPIO_ACTIVE_HIGH>;
imx6qdl-hummingboard.dtsi:  reset-gpio = <&gpio3 4 0>; (I think RMK already handles this)
imx6qdl-phytec-pfla02.dtsi: reset-gpio = <&gpio4 17 0>;
imx6qdl-sabresd.dtsi:       reset-gpio = <&gpio7 12 0>;
imx6q-dmo-edmqmx6.dts:      reset-gpio = <&gpio4 8 0>;
imx6q-novena.dts:           reset-gpio = <&gpio3 29 GPIO_ACTIVE_HIGH>;
imx6q-tbs2910.dts:          reset-gpio = <&gpio7 12 GPIO_ACTIVE_HIGH>;

The original patch was a bad implementation of a good idea.
