[PATCH v2] pci: imx: use reset-gpios if defined by device-tree

[sbabic@denx.de]

> If reset-gpio is defined by device-tree use that if
> CONFIG_PCIE_IMX_PERST_GPIO is not defined.
> Note that after this the following boards which define
> CONFIG_PCIE_IMX_PERST_GPIO in their board header file as well as their
> device-tree should be able to remove CONFIG_PCIE_IMX_PERST_GPIO without
> consequence:
>  - mx6sabresd
>  - mx6sxsabresd
>  - novena
>  - tbs2910
>  - vining_2000
> Note that the ge_bx50v3 board uses CONFIG_PCIE_IMX_PERST_GPIO and does
> not have reset-gpios defined it it's pcie node in the dt thus removing
> CONFIG_PCIE_IMX_PERST_GPIO globally can't be done until that board adds
> reset-gpios.
